This is like asking, "So, Mrs. Bach, which child is your favourite?" But as I've grown older, FOLLIES — which has a far from perfect book — is still right up there. I've listened to that score hundreds of times, and it never gets old.
Close on its heels: COMPANY. A lot more facile, I know, and certainly showing its age, but it still remains a great piece of work.
After that, it gets murky, but — and I'm prepared to be greeted with a considerable number of eyerolls here — THE MUSIC MAN. As corny as that show is, it's beautifully written. Meredith Wilson never equalled that one, which is a shame. And I dont think there's been a truly great production of that show yet. Everyone looks at it like they used to look at R&H (before the Brits got their hands on them and showed the Americans how dark and edgy these things actually were). Maybe someday someone will look at TMM and see there's a lot under the brass-plated surface.
