Nope... according to my old music teacher (who was a pro brass player and who had allegedly met the bloke), eric spears took the fees for the session when the tune was recorded, INSTEAD of getting royalties... you'd kick yourself wouldn't you!!!!
I hate to be pedantic, but in an interview with Darran Little, Corrie's official archivist, he confirms that Mr Spear passed away in 1966, but the royalties still accrue, as is his right as composer of the theme.
