Do you happen to have a link to Underneath It All live with Gwen doing Lady Saw's rap?
Hoooo boy anon this sent me into some kind of youtube spiral. Anyway basically anytime she sings it she does the rap part now. It used to be a trumpet solo for Stephen (💖💖), I believe she took it over starting with the 2009 tour. I LOVE IT.
