I tried to convince the singer this would sound wonderful done in the style of the start of 'cold days in the birdhouse' but he was having none of it.

Tindersticks - Tinseltown In The Rain

But dammit I'd love to see them try.

Speaking of NERD though, Coldplay should cover Maybe

would be my optimum piece of music.

I'll physically melt.

Pete Townsend - two little boys
Arsenal FC Fa Cup song - Its oh so quiet
Cat Power - Bills bills bills
Chris Brown - Smack my bitch up
Stone Roses - In it for the money

Amber by the Cooper Temple Clause. The mood and the lyrics would have suited him perfectly.

My Bloody Valentine - Natural Anthem

Hall & Oates doing Deon Jackson's "Love Makes The World Go Round"
Prince or Los Lobos doing Funkadelic's "I'll Bet You"

Atlantis - Supergrass
No-one knows - Morrissey
Watch that man - Suede
Here I go again - Rufus Wainwright

In return, Bellend & Sebastian covering Teachers by Daft Punk

...we deduced that Rammstein covering 'Anna' by Trio is the ultimate answer.
