A Milestone for Grand Funk
On September 29, 1973, Grand Funk’s single “We’re An American Band” climbed to #1 on the Billboard Hot 100, becoming the group’s first chart-topping hit. It was a big moment for the band, marking a shift from steady rock acts to mainstream success. The song had been released earlier on July 2, 1973, and written and sung by drummer Don Brewer.
That same year, the album We’re An American Band also rose in popularity. While it peaked at #2 on the Billboard 200, its sales and reputation grew sharply thanks to the hit single.

Behind the Hit
Producer Todd Rundgren helped polish the band’s sound, adding touches that widened its appeal without losing the raw edge Grand Funk fans loved. The move brought in more radio play and broader recognition.
Don Brewer wrote the song from life on the road. It mentions poker nights, spots like Omaha and Little Rock, and even blues legend Freddie King. The idea came to Brewer while flying into a city; he thought, “We’re comin’ to your town — we’ll help you party it down.”
Legacy and Reaction
The track was seen as an anthem of American rock. Critics and fans praised its directness and swagger. It became a staple of classic rock radio, and the performance style inspired many artists.
Though Grand Funk had made albums and toured before, this moment changed how people viewed them. “We’re An American Band” turned a working group into stars, giving them a moment that outshone earlier successes in mainstream charts.
