Wavelength

Often interpreted as a song about Morrison's travels in America or a celebration of FM radio, Van explained that it is actually about the Voice of America, which is a radio service run by the United States government for political purposes. Morrison explained to Melody Maker in 1979 that he listened to the service when he was a kid. "It's actually about Europe, because that's where the station was. It came out of Frankfurt, and the first time I ever heard Ray Charles was on the Voice of America. We tried to get a tape recording of the Voice of America to put on the front of that track, but it didn't work out. I didn't get it by the time the album was due to be mixed. But I think it would have made it a lot clearer if the signature thing was on the front of it. It doesn't click for a lot of people."

This was used on the sitcom WKRP In Cincinnati in the 1982 episode "The Creation of Venus."
