I saw MERLIN. There was a song that I still kind of remember -- "He Who Know the Way" -- sung multiple times by Edmund Lyndeck, who played a wizard. Apparently no one, though, knew the way, because the show kept extending its preview period. (Lyndeck, BTW, a few months earlier, had played Nora's lover in A DOLL'S LIFE, the Hellinger's previous tenant.) Chita Rivera played an evil queen and Nathan Lane played her cowardly son. Chita had a big song "Satan Rules," which, IIRC, ended with her -- spoiler alert -- turning into stone. Doug Henning as Merlin performed various magic acts.
I think the opening number is somewhere on youtube, as is "Step to the Rear," the big song from DOW JONES.
