I love Rihanna's 'Shut Up And Drive' and 'Umbrella'.

And Pink Floyd's 'Learning To Fly' and 'Comfortably Numb', but my all-time favourite of theirs is 'Wish You Were Here'. The words '..a walk-on part in a war or a leading role in a cage..' have haunted me for years. They seem to express a dilemma I've always struggled with.

I first got interested in Floyd while prison visiting. The young inmates were all very keen on them, and I decided to listen to some of their work. Very profound, and musically interesting too.
