After entering the Royal Air Force in 1940, McQuater found himself serving alongside Chisholm and other Heralds of Swing alumni in the RAF Dance Orchestra, unofficially dubbed the Squadronaires. As American swing began to find a commercial foothold overseas, the Squadronaires dusted off the Heralds of Swing arrangements and became a fixture on BBC radio before landing a record deal with RCA, scoring a series of hits including There's Something in the Air and South Rampart Street Parade. In the wake of D-Day, the Squadronaires were dispatched to entertain service personnel in the Northwest European campaign. So great was the group's popularity that it remained a going concern even after demobilization, with longtime pianist and arranger Ronnie Aldrich taking the helm in 1950. McQuater left the Squadronaires two years later to join the Skyrockets, then the resident band at the London Palladium. In 1953 he caught on with the BBC Show Band under conductor Cyril Stapleton, concurrently pursuing a freelance career in film and television. During the early '60s McQuater served as a member of Jack Parnell's ATV Orchestra, appearing on programs like #Sunday Night at the London Palladium. From 1976 to 1981 he was a member of #The Muppet Show's house orchestra, even contributing the frenzied trumpet work of "Lips," a player in the Muppet band Electric Mayhem. In the autumn of his life McQuater regularly collaborated with fellow trumpeter Johnny McLevy, and was a fixture of the annual Ealing Jazz Festival. His appearance at Ealing in 2004 proved his final public performance, and he died January 20, 2008, at the age of 93. ~ Jason Ankeny, Rovi
