At the end of the article in the print edition of the Star today, there's a note about a book-launch event being held on May 5 with Idsinga and the Star's Kevin Donovan. So that would be why they're just doing an article about the book now (the press release having only been about him becoming a commentator on 640 and Global).

Nice to see how well Canadian artists were represented on that CFRW chart. And even now, "The Circle Game" would still count as Canadian content for a different reason, because it was written by Joni Mitchell.

That was a second vocal version, using revised lyrics to go with the instrumental being called "The Horse". Here's the original A side, "Love Is All Right".


 

I had read about the rationale for skill-testing questions many years ago, so I did a search and found the following article that confirms what I had recalled.
Why do Canadian contests require a skill-testing question?

George Baker Selection (who were from the Netherlands) did have a second North American hit in 1975-76 with "Paloma Blanca". It reached #26 on Billboard and #5 on CHUM. 

The Archies had a total of six songs on the Hot 100, and in addition to Sugar, Sugar one other made the top 10 and two more made the top 40. In chronological order, they were as follows:
#22 Bang-Shang-A-Lang
#53 Feelin' So Good
#1 Sugar, Sugar
#10 Jingle Jangle
#40 Who's Your Baby?
#57 Sunshine

The De Tupelo a Memphis website has some relevant info about this which I'll excerpt below. The DJ who introduced Elvis, Josh King, was the host of a country music show on CHUM.

[b]CHUM Radio, through the disc jockeys invited listeners to send in their reasons for wanting a date with Elvis, it was a sort of contest .Everything was party and The best entries would win the chance to meet Elvis backstage . Photographs were sold, etc. 
But it was not all positive as an anti-Elvis club in Tennessee tried unsuccessfully to convince Toronto DJs to stop playing Presley records. Security was paramount and a large security force of ninety-five officers was assembled in Toronto, the largest security force ever provided to be in the arena during the show. Several special "flying squads" were organized to go around the arena and stop trouble before it could start. They were ordered to eject anyone who got out of their seat. But the tricky part was to empty the arena quickly during the first show so that at 9.00 pm the second show could take place. The funniest thing would be the mystery that Elvis' arrival in the City offered, since when April 2 dawned in Toronto, the headline of the "Toronto Daily Star" wondered. "Where is Presley! He can't be reached. The paper could not find out how Elvis would get to the city, let alone where he would be staying. 
No one knew it was a secret or at least no one leaked that information so Elvis could arrive quietly without harassment. It was only known that at 06:00 p.m. Elvis would have to be at Maple Leaf Gardens for his performance, but Elvis had already arrived and was sleeping in a room on the fifth floor of the King Edward Hotel. The secrecy was short-lived, though, because the hotel secretaries gathered to head to his room, where a pair of bodyguards politely blocked their way. The show is about to start and local disc jockey Josh King takes the stage to introduce Elvis , the crowd

I think that Sedaka reaching the top 10 twice with two completely different versions of the same song is the most remarkable single instance of an artist doing this. However, Tommy Edwards made the top 40 on Billboard three times with very different versions of his hits "It's All In The Game" (1951, 1958), "The Morning Side of The Mountain" (1951, 1959), and "Please, Mr. Sun" (1952, 1959). Of course the originals of all three songs predate the CHUM Chart, but there is another instance of this kind of feat occurring during the CHUM Chart era: The Ventures with "Walk-Don't Run" and "Walk-Don't Run '64". Also noteworthy is that on Billboard, the two versions had almost the same chart peaks as what Sedaka achieved; The Ventures' original got to #2 in 1960, and their remake reached #8 in 1964.

This reminded me of when Nancy Walker had significant roles on both McMillan & Wife and Rhoda, because I thought at the time that this was quite noteworthy. From her Wikipedia entry:

When the MTM spinoff series Rhoda premiered in 1974, Walker was a regular cast member in 41 episodes.

From 1971 to 1976, she was a regular on the successful Rock Hudson detective series McMillan & Wife, playing the McMillans' housekeeper, Mildred. During the first two years of Rhoda, Walker was not featured every week, so she was able to shuttle back and forth between the CBS sitcom and the NBC detective series. These two roles brought her seven Emmy Award nominations.

"Competition Ain't Nothin'" also spent 6 weeks on the CHUM Chart, peaking at #11. 

According to The CHUM Chart Book, "The President's Canada Conference" by Garry Ferrier charted for 4 weeks, peaking at #28 on January 7, 1963.

Since I was born in 1960, I don't have firsthand memories of what was making the CHUM Chart in 1966-67. However, many years ago I had been curious about whether "Double Shot Of My Baby's Love" had charted on CHUM, and when I looked it up in The CHUM Chart Book I found that it wasn't listed. Just checked the listings for The Rolling Stones, and "Let's Spend The Night Together" isn't shown either.

Blue Jays was the name of the album that was issued as being by Justin Hayward and John Lodge. But it was a clever name that alluded to them being members of The Moody Blues who had first names begining with J.
