Music from "40" - Channel 4 Drama

[trybus04]

Does anyone know what the catchy music from the Ch4 drama "40" starring Eddie Izzard is (or how to get hold of it)?  A previous answer in AB suggested it was by a guy called 'Robert Folk' but I can't get that verified on the net and I've found something crediting a "Simon Rogers" of Faber Music but his music from the series isn't the bit I remember.  This is doing my head in.  The bit of music was also included halfway through a Boris Becker documentary screened on BBC1 at 11.45am on Monday 20th June 2005.  Anyone any ideas?  Thanks/
