This changes all the time of course, but currently it is "Robbie Williams, Swing while your Winning" CD.
An absolutely outstanding recording....but moreover it really puts the "fun" back in music! (unlike many pop, classical, jazz, acoustic or rock genre's that take themselves all too seriously)
A pleasant dusting of duets, a bit of broadway, some great energetic Basie Band arrangements and of course, plenty of swing.
I was shocked that Robbie could pull this swing thing off so well.
