Any time Rob Brydon "accompanies" Tom Jones, but especially "Delilah". He sings along with Jones' vocals... and then it drops out and he continues on with an absolutely perfect imitation. And then, when the music picks up again, he's completely in time.
Pretty much any time Brydon sings is a Crowning Moment of Awesome for him. He shines when singing One Song To The Tune of Another, whether it's Madonna's "Hanky Panky" to the tune of "Fly Me To The Moon" or the poem "You Are Old, Father William" to the tune of "I Know Him So Well", during which he hit a fabulous high note.
"Anarchy in the UK" to the tune of "Just When I Needed You Most".
In one early edition, Graeme Garden accompanies George Formby to "When I'm Cleaning Windows". He does the first verse fairly well, with a pretty good impression, but then he messes up the words and loses his place. He starts chatting idly to the other panellists, before starting to sing again — and when the record comes on again, he's perfectly in time.
David Mitchell singing the words of "A Whiter Shade of Pale" to the tune of theme from The Muppet Show. The result is epic.
Pick-Up Song. Graeme singing "I Don't Feel Like Dancin'" by Scissor Sisters. He puts on a posh accent while the music drops out, making you think he's just joking around...and then the music comes on, and he's absolutely in time. Really, any of the times that the panellist has had to keep singing for a while after the record is turned up for the audience to be able to tell the difference between them and the record is utterly awesome.
Another Pick-Up Song: Tim has to sing "You Don't Have To Say You Love Me" by Dusty Springfield. Unfortunately, the music cuts out immediately after the brassy introduction, leaving Tim with no lyrics to start singing to. There is huge laughter. Tim is momentarily shocked, rushes into the song, mutters a venomous "bastards!" between lines, and carries on valiantly. The record comes back, and Tim is almost perfect. Huge applause follows.

Any time Humph got to play the trumpet was invariably fantastic.
