Apologies if this is done before, but figured it would be fun and require some thought about lineup changes that did not materialize. A number of these have turned up in other threads (ie guitarists to replace Mick Taylor in the Stones). So, let's collect them all in one place! Might as well start with Mick Taylor's potential replacements. Have seen Jeff Beck, Mick Ronson and Rory Gallagher mentioned, with probably others, before Ronnie Wood got the job. Supposedly, Steve Marriott was Jimmy Page's first choice as singer for Led Zeppelin. Have also seen Terry Reid's name linked with 'the New Yardbirds,' and apparently, he's the one who recommended Robert Plant to Jimmy Page. Not sure if the vision was to have 2 guitarists, but the history is fascinating, nonetheless. Bryan Ferry and Elton John (yes, really) auditioned for vocalist jobs with King Crimson. No doubt, there are plenty of other examples from this band's history. Jerry Marotta was planned to be the drummer, before Bill Bruford returned to the fold in '94. Alfonso Johnson auditioned for the live bass player gig with Genesis, but Mike Rutherford & Co. wanted somebody who also played guitar. AJ suggested Daryl Steurmer get in touch. Before settling on Carl Palmer, Keith Emerson and Greg Lake were considering Mitch Mitchell. That led to interest in Jimi Hendrix possibly joining the fold. Speaking of Hendrix, Mile Davis wanted to work with him, too. Hopefully, somebody else can share more about the details. OK, team, bring more on!
