In 1952 Grainer left Australia for London with his wife Margot and 10-year-old stepdaughter Rel. He managed to find a three-month engagement playing piano in a nightclub along with other occasional jobs, the worst of which became a twelve-month stint with a touring Australian comedy act called "The Allen Brothers and June." This required the classically trained Grainer to be hit on the head nightly by a falling grand piano lid and then to topple over into the orchestra pit, an experience he later said was even harder to do than a day's fencing in the Australian outback.
