"Sunday Night at the London Palladium" from 1974.
Hosted by Ted Rogers who in his day was an amusing, if not sensationally funny, comedian.
The first act was Scottish singer/impressionist/comedian Allan Stewart whose name I didn't recognise but whose face I did. He was a very decent turn with a melodious singing voice and some skilful and funny impressions.
The second act was The New Dollys - three elegantly dressed, high-kicking American girls who rode bicycles around the stage pursued by a grey-haired man in a suit (also on a bike). To finish off their act, the grey-haired man with one of the girls on his shoulders and another girl on her shoulders rode around the stage on what must have been the smallest bike in the universe!
Ted Rogers then told some jokes about Mother's Day. The most interesting joke (from a "how times have changed" perspective) was about two hippies he'd seen in a shop buying Mother's Day presents for their fiancées.
Do you get it? Hippie couples were having children out of wedlock!
Next on stage was Irish singer Clodagh Rodgers who I always thought underrated.
She had three record hits within a couple of years around 1970 but then, to a great extent, faded from the public view despite a few appearances on TV with high profile celebrities during the 1970s. That was a shame because she had an excellent singing voice, she was exceedingly pretty and she seemed to be a very nice girl indeed. As if all that were not enough, she could do very good impressions of other singers. Very much a highly-talented "girl next door" type who I remember with fondness.
The headline act was Mike and Bernie Winters who, as comedy double acts go, were very good in their day - largely due to Bernie, of course.
A lady friend of mine once saw Bernie Winters in a restaurant in Manchester and told me she was amazed how good-looking he was in real life.
