The excellent Musical Motifs in New Who has been updated with all series 4 music including the songs in The Unicorn and the Wasp in which I previously identified the Cryin’ All Day by Frank Ricotti and his All Stars as being heard near the beginning.

However, it is identified on the site as the Beiderbecke version since William Gallagher phoned no less than Alan Plater himself having, like me, identified it as the title track to The Beiderbecke Trilogy and called to get information on the recording.

I am convinced I’m right (naturally), and am investigating the matter further.
