I have time today, so gonna keep the ball rolling here (but feel free to keep discussing the previous tunes, too)...
Peter Frampton - Do You Feel Like We Do
Can you imagine a 14-minute live song being such a huge hit nowadays? No chance in hell. And it just shows how different the musical climate and rock radio was back in the 70s. To this day, I don't think I've ever heard the studio version of this song, as the live version was always the one that was played everywhere here, and it is one helluva song. Granted, it is now a song that I rarely listen to, but on the rare occasions that I do, it still sounds pretty awesome. This song is probably the most well-known and successful use of the talk box ever.
