In September 1976, Mullen put an advert onto the school's bulletin board seeking other musicians to form a band; Clayton showed up for the first meeting and practice, as did the Edge with his older brother [[Dik Evans|Richard Evans ("Dik")]], Bono, and Mullen's friends Ivan McCormick and Peter Martin, who both left the band soon after its inception.<ref name="mcc40"/>

While the band was a five-piece (consisting of Bono, the Edge, Mullen, Dik Evans, and Clayton) it was known as "Feedback". The name was subsequently changed to "The Hype", but changed to "U2" soon after Dik Evans left.<ref name="bio1">{{cite web |url=http://www.atu2.com/band/bio.html |title=U2 Biography from @U2 |access-date=10 September 2007 |last=McGee |first=Matt| archive-url= https://web.archive.org/web/20070917034205/http://www.atu2.com/band/bio.html| archive-date= 17 September 2007 | url-status= live}}</ref> Clayton stood in as the nearest thing that the band had to a manager in its early life, handing over the duties to [[Paul McGuinness]] in May 1978.<ref>McCormick (2006), pp. 52–56, 59–62</ref> In 1981, around the time of U2's second, spiritually charged album, ''[[October (U2 album)|October]]'', a rift occurred between Clayton and McGuinness, and the three other band members. Bono, The Edge, and Mullen had joined a Christian group, and were questioning the compatibility of rock music with their spirituality.<ref name="bio1" /> However, Clayton, with his more ambiguous religious views, was less concerned, and so was more of an outsider.

In 1995, after the [[Zoo TV Tour]] and ''[[Zooropa]]'' album, Clayton went to New York with bandmate Mullen to receive formal training in the bass; until then, Clayton had been entirely self-taught.<ref name="book2" /> During that period, Clayton worked on U2's experimental album, released under the [[pseudonym]] "Passengers", entitled ''[[Original Soundtracks 1]]''. That album features one of the few instances where Clayton has appeared as a vocalist; he spoke the last verse of "[[Your Blue Room]]", the album's second single. Prior to this Clayton had only provided live backing vocals to tracks such as "[[Out of Control (U2 song)|Out of Control]]", "[[I Will Follow]]", "[[Twilight (U2 song)|Twilight]]", and "[[Bullet the Blue Sky]]". Since the 1997 [[PopMart Tour]], Clayton has not sung live in any capacity for the band.<ref name="rs">{{cite magazine |url=https://www.rollingstone.com/music/artists/u2/biography |archive-url=https://web.archive.org/web/20110619060444/http://www.rollingstone.com/music/artists/u2/biography |url-status=dead |archive-date=19 June 2011 |magazine=[[Rolling Stone]]|title=U2: Biography |access-date=1 January 2011}}</ref>
