Spinal Tap’s Derek Smalls on Pepto Bismol, Phone Sanitation, Paul McCartney, and His New Single “Must Crush Barbie”

Fans (well, some) fell in love with bass player Derek Smalls when they encountered him in the film, This Is Spinal Tap. The bass player for the iconic group (Spinal Tap) has been a leader in all things hard rock ever since. More recently, the musician has released his latest single, the pink-bashing “Must Crush Barbie.”

We caught up with Smalls to ask him about his history playing bass, the origin of the new anti-Barbie song, what he thinks of Paul McCartney’s violin bass, and much more. Smalls even talked about his childhood growing up and his affinity for the letters LSD.
