Endersby remained with the band as it evolved through The Tripp and Livingstone's Journey but left for England in March 1968 where he met Kinks bass player Peter Quaife who invited him to form a new group.
The promised band, however, never materialised and later that year he returned to Toronto to produce the music for Jim Henson's TV show "The Cube".
After a brief stint playing with Transfusion (the house band at Toronto's Rock Pile where they opened for Frank Zappa's Mothers of Invention as Crazy Horse – no relation to Neil Young's group), he received a call from Quaife asking him to return to England and put together the promised band, Mapleoak.
Mapleoak initially comprised English drummer Mick Cook and Canadian keyboard player Marty Fisher who had played with Endersby on "The Cube".
The band also comprised ex-The Paupers bass player Denny Gerrard, drummer Pat Little from Luke & The Apostles and Chimo!, guitarist Gary Holmes and future Motown star, singer Rick James.
