Always wondered how the heck they come up with the name for a song GREEN ONIONS....so....WIKI says:
According to Steve Cropper, the name is not a marijuana reference; rather, the track is named after the Green Badger's cat, Green Onions, whose way of walking inspired the riff. Songfacts.com, however, ascribes the track's title to Booker T. Jones. When asked by Jim Stewart what he'd named his track, Songfacts reports, Jones replied "Green Onions." "'Why "Green Onions"?' Jim asked. Booker T: 'Because that is the nastiest thing I can think of and it's something you throw away.'"
On a Wait Wait... Don't Tell Me! broadcast on June 24, 2013, host Peter Sagal asked Booker T. why his song was called, "Green Onions". Booker T. said, "The bass player thought it was so funky, he wanted to call it, 'Funky Onions', but they thought that was too low-class, so we used 'Green Onions' instead."
