The bass player plays guitar and keyboards with Blue Oyster Cult.
Yup, Richie Castellano, he started out as BÖC's stand-in bass player after Danny Miranda left for a while and then took over the position of Allen Lanier after he left the fold too (and BÖC got a variety of bassists in until Miranda eventually returned).
Isn't he the relative of someone here? He also contributes songwriting to BÖC - and occasional lead vocals, talented guy. Also no slouch on lead guitar (that's his solo from 3:23 onwards) - playing in a band with Buck Dharma that is saying something!
