Anthony didn't have throat cancer, he had non-Hodgkins Lymphoma (a virulent form of cancer/leukaemia) which he has (so far, fingers crossed) successfully beaten.
My personal favourite is Anthony Warlow. I love his interpretation of J&H on the complete studio recording, he *is* that CD! He puts so much feeling, emotion, depth into those characters. It's worth coping with some totally naff lyrics to listen to Anthony.
Oh and him and Philip Quast singing 'Lilys Eyes' is terrific

For me, personally, Michael is a better singer than actor. 'Passion' sounds better on CD than it was on stage for me, he can act with his voice. Michael couldn't get rid of his 'michaelisms' - mannerisms he has on stage in his solo concerts. Also he didn't seem completely comfortable in his role in CCBB, especially interactng with the kids.
But, hey, lets enjoy them both on their own merits
