One door on stage and the play can be comedy or tragedy. Two or three doors on stage and it's a thriller. But six doors on stage points to only one genre - farce.

"Lend Me a Tenor" at Broadway's Royale Theatre has six (count `em, six) doors confronting the audience, each of them hilariously changing the plot.Like the plots of all farces, this one is dumb, dumb, dumb. In a hotel suite in Cleveland in 1934, the world's greatest tenor (Ron Holgate) is about to make his American debut, as Othello.

He arives late, tired and sick. But too many attendants, each giving doses of sleeping pills, render the patient comatose. Indeed, he is thought to be dead.

Panic strikes the impressario (Philip Bosco). He reacts to bad news the way a blimp does to a a spear. Apopleptic with rage and fear, he cajoles his wimpy hanger-on, Max (Victor Garber), to impersonate the tenor.

"Lend Me a Tenor" is a light and airy souffle. If farce neeeds an accolade, it's a door-slammer!
