a pretty good interview with Bolder is in the new issue of the UK BassGuitarMagazine
he says he lent Pino Palladino a fretless bass for his audition with Jools Holland, which he didn't like- and later became renowned for fretless,
also that he lent John Entwistle his Trace Elliot valve amp- but then Entwistle died, and the amps got taken by the estate- and sold in the famous auction!
