The band embarked on a brief tour of Boston with Mountain in early April. Luke & The Apostles then returned to Toronto to play at the Electric Circus on May 9 after which McKenna left to rejoin his former band, now going by the name Mainline. The group then appeared at the "Peace Festival" at Varsity Arena on June 19–21 with Rare Earth, the SRC, Bush, George Olliver & Natural Gas, Nucleus and others before McBride also departed. He later became a member of Chris De Burgh’s backing band.
