Sherlock Holmes hasn't had an easy time of it on the musical stage. The most prominent example of attempts to put Sir Arthur Conan Doyle's master sleuth above an orchestra pit, 1965's Baker Street, struggled along on Broadway for nine months before closing at a major loss. The same year, the eight-performance Drat! the Cat! managed a "Holmes and Watson" song more delightful than anything in Baker Street, but it was a throwaway number in a daffy musical comedy about something else. A 1988 Sherlock Holmes: The Musical, written entirely by Leslie Bricusse, managed a few months in the West End. In all cases, the main problem appears to have been that the famously analytical, reserved Holmes isn't a naturally singing character. On the Baker Street cast album, Fritz Weaver talk-sings in clipped consonants, sounding uncomfortably like a far less interesting Henry Higgins, and Marian Grudeff and Raymond Jessel ain't Lerner and Loewe. . . .
