Ritchie grew up in the Scottish village of
Forth in Lanarkshire. He began playing harmonica at an early age, and when a neighbour threw out a piano, and Ritchie's parents took it in, Ritchie, at the age of 8, began playing semi-seriously, but as an almost secret activity. In 1960, Ritchie's friends, Johnny Moffat (vocals), Robert 'Flam' Fleming (guitar) (b. December 1943), William 'Big Wull' Ritchie (guitar, Billy Ritchie's cousin), Jim Stark (drums), and Duncan Blair (bass), formed a band called The Satellites. When asked what he would play, Ritchie decided to play
electric organ, much to the bemusement of his friends. Organs were not in common use in guitar-orientated bands of that time. In 1964, a band called The Premiers, based in Edinburgh, whose members were Ian Ellis (vocals), James 'Shammy' Lafferty (rhythm guitar), Derek Stark (lead guitar), Bill Lawrence (bass), and Harry Hughes(drums), decided to recruit an organist to augment their sound, and Ritchie joined. The addition prompted more changes than was intended, and despite an early success in being recorded at
Radio Luxembourg in London by
Cyril Stapleton, the band quickly fragmented. Derek Stark left because he felt that the organ had supplanted his role as lead musician; Bill Lawrence left following a dispute with Ian Ellis; James 'Shammy' Lafferty left because of family problems. The three remaining members, Ian Ellis, Harry Hughes, and Billy Ritchie decided to take the music in a radically new direction, and renamed the band
1-2-3. 1-2-3 was one of the earliest bands to play a form of inventive rock music that became a blueprint for what would later be called
progressive rock. The band's set consisted of standard pop and blues songs, but in Ritchie's hands, these pieces were studiously reshaped and rewritten, to become, in essence, new. There was nothing remotely like it around. The set included early rewritten versions of songs by
David Bowie (
I Dig Everything) and
Paul Simon (
America,
The Sounds of Silence), both completely unknown at that time. Some months after their debut at La Bamba club in
Falkirk, 1-2-3 decided that the band would have more chance of success in London, where they arrived in February 1967. A 'legendary' residency at the Marquee club quickly followed, and the band were signed to
Brian Epstein and
NEMS management. Following Epsein's death however, manager
Robert Stigwood failed to capitalise on the momentum of the Marquee performances, and the band left NEMS late in 1967. 1-2-3 was then signed to The Ellis-Wright Agency, which would soon be called
Chrysalis, and the most commercially successful part of the band's career began, under the new name of
Clouds. Several major tours and three albums and several single releases followed, but real success proved elusive, and the band broke up in October 1971. ==Instrumentation and playing style==
