Chicago/Caberet - Kander & Ebb with Bob Fosse choreography is just brilliant, also La Cage Aux Folles, saw that in London & loved it.
That said, I also love the old-style musicals of stage and screen; Fred & Ginger movies, High Society, Kismet, etc., and G&S.
I used to do a bit of am-dram musicals and even got to reprise the same role in The Boyfriend after ten years (that's when i decided it was probably time to quit!) and at the time I listened to/watched a ton of musicals and liked everything from Offenbach to Lloyd-Webber & Cameron Macintosh.
But please, please, never make me go near Carousel or South Pathetic...yeugggghhh!
