Hi Peggy, great to see you at Cropredy and on here.
As there appears to be a whole branch of mathematics devoted to who you've collaborated with, for example a quick search brings up this page

I was watching Peter Gabriel's 'Growing Up' tour DVD the other night and if it's possible to fit 2 bassists on one stage, Tony Levin is one candidate from my point of view. (What's the collective noun for bass players btw?)
