Ah @Poppikok - that was Happidrome, with Harry Koris (Mr Lovejoy), Cecil Fredericks (Ramsbottom) and Robbie Vincent (Enoch - "Let me tell you-o-o").
Broadcast from Bangor in the early days of WWII, it featured every available Variety star, in the framework of the imaginary Happidrome variety theatre, run by the three staff members. The 'We Three' sig tune was a parody version of My Echo, My Shadow and Me, by Dick Robertson and Sammy Mysels, a popular hit by The Inkspots.
Ramsbottom: I say, do you know anything about love, Guv'nor?
Lovejoy: I should do - I drove a taxi for five years...
