Johnny McClanian Best, Jr. (October 20, 1913, Shelby, North Carolina – September 19, 2003[1]) was an American jazz trumpeter.
He worked in the 1930s with Les Brown, Charlie Barnet, and Artie Shaw (1937–39), then joined Glenn Miller's orchestra from 1939 to 1942.
He spent a short time with Bob Crosby before serving in the Navy during World War II as a lifeguard, playing in Shaw's military band in 1942-43 and Sam Donahue's in 1944-45.
Following a stint with Benny Goodman in 1945-46, he relocated to Hollywood, where he worked with Crosby again on radio from 1946 to 1951 and played in many studio big bands in the 1940s and 1950s.
He played the trumpet solo on the Glenn Miller recording of "At Last", which was featured in the film Orchestra Wives, lip-synched by George Montgomery on screen.
