Ah well. This has been an either or story for nearly thirty years now. Here's the unbiased version. This will have to be a two-parter so I will post this accordingly. 'Faith. No More' (full stop in name is official, the quotes aren't) was created n 1979 by M Morris and Wade Worthington. Drummer extraordinare Mike Borden was recruited next followed much later by Bill Gould. (To go back even further, the original name was 'Sharp Young Men' as a piss-take on all the 'elegant' 80s groups at the time.) Originally Morris proposed 'Faith In No Man' but after much back and forth, Bordin rightfully suggested 'Faith. No Man'. Morris became very hard on Gould which eventually caused a rift in the band. Worthington left the group because of the tensions and because he felt unsatisfied with his own contributions. Many possibilities were bandied about including adding a second guitarist - Jake from Crucifix. [Please see next entry]
[Continued] But it was mutually decided Gould's childhood friend Roddy Bottum was to became the new member. At that time, being fully aware of the rift, Bottom quickly fell inline with the three and eventually plans were afoot as to how to carry on without Morris because it was his band and he was now the sole songwriter and singer within the group. After the final show, there was no communication again between the three and Morris for six months. Bordin then contacted Morris and though not in touch regularly, they have been able to remain friendly over the years. So rather un-dramatically, the band simply broke up. Anything else is just post-split invented angst. Morris was never called 'The Man'. There has been no contact between Gould, Bottom and Morris although Gould regularly dines at one of Morris' dearest friend's restaurant in SF! I mention this now not only to try and set the record straight but because it is the 30th Anniversary of the birth of Faith. No Man. (1979-1982)
I'd read in a few places that instead of firing Mike Morris, all other members of Faith No Man quit and then someobody suggested the name 'Faith No More' for their band because "the Man" was "no more"...so that sort of suggests that they're different bands but that Faith No More was a reincarnation of Faith No Man, because Faith No Man died when Gould, Bordin, Bottum etc quit the band. I also read that Faith No Man's original keyboardist was Wade Worthington, not Roddy Bottum. But now almost everywhere I look it says that Gould etc fired Mike Morris and then changed the name of the band, and there doesn't seem to be any mention of Wade Worthington.
I guess you could say that Faith No Man and Faith No More aren't/weren't exactly the same band, but at the same time sort of are/were because quiting Faith No Man worked out just as if Mike Morris had been fired.
