My personal preferences in scores (not lyrics...Menken wrote the music for Hunchback):
Godspell
The Baker's Wife
The Magic Show
Wicked
Pippin
Children of Eden
I love the original score to Magic Show (not the revised score featured in the DVD), but I hate the book with a passion. To me, the only weak song in the score Sweet, Sweet, Sweet. I've never been much of a fan of Pippin. I like a few songs, but I can't stand the book and without the collaboration of Ostrow and Fosse, I think it would have been an absolute train wreck. Godspell was innovative for its time and the score has always been the reason for its longevity. And The Baker's Wife is one charming melody after another with a few out-and-out brilliant numbers. Wicked has some weak numbers, but the strong numbers are golden. I enjoyed seeing a nice local production of Children of Eden, but none of the songs stay with me at all no matter how many times I revisited the recording. It's just forgettable.
As for his lyrics and ability to write funny songs, I think he succeeded numerous times in Wicked, The Magic Show, Enchanted (film), Rags and Pippin.
