Haven't seen it, but 'Wonderful World' not listed in my copy of 'Sight and Sound'. Definitely in it is 'We Have All The Time In The World' by David Arnold featuring Iggy Pop. Perhaps that's it.
What's with the visuals in the credits? Is it supposed to mean something (the credit visual? I thought the film was one of the very best I have seen in ages. Thank God for Channel 4 film reviews!)
Sight & Sound is the official monthly film mag from the bfi. Along with various articles it contains plot synopses, reviews and full credits for every film released in the UK. http://www.bfi.org.uk/sightandsound/index.html
