I agree it should be "lightly" not "likely". This wasn't a Goons sketch but a Peter Sellers solo piece from the album Best of Sellers. This was a 10" LP (remember them folks?) on Parlophone, produced as stated above by George Martin. It was later reissued as a (by then more conventional) 12" LP.

Tracks: THE TRUMPET VOLUNTEER / AUNTIE ROTTER / ALL THE THINGS YOU ARE / WE NEED THE MONEY/ I'M SO ASHAMED / PARTY POLITCAL SPEECH / BALHAM - GATEWAY TO THE SOUTH / SUDDENLY IT'S FOLK SONG

I would have thought the last one would have been of the most interest to this group! It featured a German "collector" of UK/Irish folk music, including a Somerset singer (recorded in a Somerset 'bierhaus'), a Scottish singer (Hamish McPukes, recorded on the corner of Sauchiehall Street with some 'traffics noise') and an Irish ceilidh band (Pat O'Shaughnessy and his Men of Shamrock).

A great little album, with every track a comic gem, IMO!
