Guess what Paradise would sound like..

[getithom]

I'm guessing the actual instrumental portion of the song will consist of strings and a catchy piano riff at the beginning. About 30 seconds in, Guy's bass will kick in and then gradually build up into a full-band sound (I'm thinking a blend of Viva, DaAHF, and Glass Of Water) for the chorus. For the bridge, Will and Jonny will fade out, leaving the piano, bass, and a very quiet string instrument (perhaps a cello). It will then swoop back into the chorus and a piano or guitar riff to finish out the song.

 

You were actually pretty accurate, here.
