In our interview with Grand Funk drummer and vocalist Don Brewer
, he explained: "The idea of Locomotion came when we were working on the Shinin' On
album in the studio with Todd (Rundgren). We had basically finished the album - 'Shinin' On' was going to be the first single, and we were thinking about what we were going to do for another song. Mark (Farner) came in one day and off the top of his head was singing, 'Everybody's doing a brand new dance now,' just for fun, and we all went, 'Yeah, Grand Funk doing the Locomotion.' It was a tongue-in-cheek kind of thing, and we said, 'Let's try it, let's do it,' so we sent off to New York, got the lyrics, and Todd had the idea of doing the song kind of like The Beach Boys' 'Barbara Ann' where it sounded like a big party was going on, except Todd could really crank up every thing with the hand claps and all of that stuff. It just had this huge sound to it - it sounded like a big party."
