I wouldn't call John F's work on Under the Bridge virtuoso in the least, but it was certainly an iconic song for guitar, and being able to play Under the Bridge reasonably well is pretty standard for any guitar player moving into intermediate level who is a fan of rock music. Jerry was a Racecar Driver on the other hand probably less than 0.2% of bass-players can play. Trolling aside, SAHW did pretty well especially considering she sang while playing. I just wasn't that big a fan of her voice.
