Whoa, this brings back memories.
This was a pleasant little hour-long variety show from the UK that aired for a couple of summers in the early seventies on US network TV.
Things I remember:
Des O'Connor, a very engaging personality, midway through a song inviting his audience to "sing to Desmond."
I Say I Say I Say: A rapid fire series of setups and punchlines delivered by regulars and guests as they stroll through a set; each humorous exchange began with one passerby accosting another with the words "I Say I Say I Say..."
I'd love to see a rerun of this show, haven't see Mr. O'Connor in 30 years, though apparently he's continued to enjoy a long career in the UK.
