I love Elaine but seeing her and Barbara doing I Know Him So Well from years ago I chuckled - I called them Hinge and Bracket at the time; she's so tiny, Dickson is tall and they did look like drag queens.

Kate Robbins and one of her sisters did a brilliant parody on their TV show. I have it on VHS and will try to upload it to the net
It went like this.

(Elaine) Standing here I feel her presence constantly
I am only 5 feet in my socks
(Barbara) I must be 6 foot 7 easily
(Elaine) I'm sure she's standing on a box

Chorus:

(Elaine singing) isn't she huge ?
(Barbara singing) isn't she small ?
(Both) Don't we look daft like Cannon and Ball
(Elaine) I wish I had a partner who should ask like me instead of her
(Barbara) I'm sick of singing with a midget
(Both) My god she's so (At the same time) : (Barbara) Small (Elaine) Tall
