"Do I Do" (1982) was Watts on an electric bass.
"That was done at Wonderland. Stevie was real comfortable with the whole band at that point, so we just went in and jammed and played what we wanted. He gave me more freedom on that song than on just about any other, and with [drummer] Dennis Davis laying it down strong and simple, there was a lot of room for me to stretch. I used my ’79 MusicMan StingRay, recorded direct, with no effects. The nasty, growly sound is just the tone of the bass, plus the strings being tuned down to Eb, which added more rattle and fret noise. In the video we shot, they had us all in black on a dark background; I wore a white cowboy hat because I wanted to make sure I got seen!"
