Guitar legend Shuggie Otis played bass on what famous instrumental rock song? Here’s a hint. It’s the opening track on an album titled Hot Rats. The answer is… "Peaches En Regalia" by Frank Zappa. It’s rollicking. It’s funky. And It’s arguably Zappa’s best-known song, or at least the most covered… there’s over twenty known recorded versions of it! What’s amazing about the song is it sounds like it’s being played in a room full of musicians, but what you’re hearing is the work of four people… Zappa, multi-instrumentalist Ian Underwood, drummer Ron Selico, and blues guitar virtuoso Shuggie Otis, who was 16 years old at the time of the recording.
