Theme to 663 Sqn - whistled it many many years ago whilst doing first solo
I take it you mean 633 Sqdn.....
That's my wake up music in the car when I drive to work. Ron Goodwin, superb and often overlooked composer. He also did 'Those Magnificent Men In Their Flying Machines' and did some of the incidental music for 'The Battle Of Britain', the main theme being of course by Sir William Walton, so he did his bit for aviation in his own way.
