This is not the first time I've heard this on the soon-to-be-extinct Roy Green Show. In several bumper music intros on the show, which is being produced out of CKNW in Vancouver, it's very clear there is a second track missing. For instance, they just played Van Morrison's "Brown Eyed Girl," a huge hit and a very well known track. It's impossible not to know what it sounds like, even in mono. 

And yet, when they played it as a rejoin to the show around 2:30 PM Sunday, it was obvious it sounded nothing like the original because part of the track was missing. I heard the same thing on Saturday, when they played Norman Greenbaum's "Spirit In The Sky intro," another famous tune. But it sounded totally different with only half the track playing. 

I've heard this occasionally before in this show and I've always wondered: how is this possible? Why wouldn't the full track, the one every listener is familiar with, play over the air? What is the cause of this and are they even aware of it? If it wasn't a famous song, you might not notice. But when it is, it stands out like a sore - um, ear.
