Both Jack Lancaster and Robin Lumley are two musicians who in the seventies made a name for themselves working on various albums within the progressive rock as well as the jazz rock sphere. Together Jack Lancaster and Robin Lumley formed a team, composing music for TV and playing together in various sessions. Between 1975-1976 they teamed up to release two albums, with the help of other illustrious names, that have left their mark on the progressive rock world.

The first band that seems to have existed which sees both Lancaster and Lumley together was a studio band called The Soul Searchers which also included within its line-up John Goodsall (guitar), Gary Moore (guitar), Percy Jones (bass) and Bill Bruford (drums). Lancaster and Lumley wrote the two songs that appeared as a single in 1975, Scaramouche / Head Stand (1975, EMI).
