The Drowsy Chaperone

The Drowsy Chaperone by Bob Martin & Don McKellar; music & lyrics by Lisa Lambert and Greg Morrison.
The Drowsy Chaperone, a comic "musical within a play," is an homage to American musicals of the jazz age. It won 8 Tony Awards in 2006 including best book. The Man In The Chair, a mousy agoraphobic Broadway fanatic seeking to cure his "non specific sadness", listens to a recording of a fictional 1929 musical comedy, "The Drowsy Chaperone". As he listens to this rare recording, he is transported into the musical. The characters appear in his dingy apartment, and it is transformed into a Broadway set. From time to time the Man in the Chair tries to insert his extensive but trivial knowledge of musical performances and actors. This is a fall off your chair funny musical farce.
