After the release of Shamblejam in 1975 the band were at a low ebb, struggling to stay in business.
Although the album was their first to be released in the USA and is one of the great prog folk albums of the 70s, their US-based label Myrrh do not appear to have granted them a US tour. This was not to take place until November 1977.
Sometime in 1976 the British label Pilgrim came to the rescue. Brian Smith had left and John Pac and Sue McClellan took on Pete Yates-Round after meeting him in Holland.
Pilgrim hired the three musicians as a production team with John Pac as head of production. There is some confusion as to what point the Grapevine label was launched as many of the releases seem to have been under the Pilgrim label.
By the time of the release of Rehearsal for a Reunion on Grapevine in late 1977 the trio had been involved in the production of some 40 albums. The three provided guitar, mandolin, drums and backing vocals on many of the records - Pac was the mandolin player and Yates-Round the drummer. The range of output is said to have included choral and classical work.
Examples of the work included: Stewart and Kyle Yours Ever, producer Pac; Koinonia Gentle as Morning, producer McClellan; Ben Forde The Supreme Sacrifice, producer Yates-Round; Rufaro Rufaro, producer Pac.
Stewart and Kyle were quite well known, Koinonia was an Irish choir whilst, judging by their album cover, Rufaro may have been a heavy metal band.
