Grand Funk Railroad, "We're an American Band" (1973)
In a bar in Baton Rouge, Grand Funk Railroad got into a late-night argument with Humble Pie: Which was better, British rock or American rock? Grand Funk drummer Don Brewer touted Jerry Lee Lewis, Fats Domino, Little Richard and Elvis Presley, then declared, "We're an American band!" Once Brewer sobered up, he turned that nationalist sentiment into a song, and when the band went into the studio to record it with producer Todd Rundgren, Brewer — not the band's usual singer, Mark Farner — did the vocals. The single hit Number One and became Grand Funk Railroad's defining anthem.
