The songs would be recited, without music, by the
on a stool smoking a cigarette.
When the stage hand rushed on stage with a stool, a
of cigarettes and a lighter you'd say "Oh,
a song so we can get a break from the awful, nonstop
music." The obvious advantage of this is being you'd
FORWARD to the songs in musicals.
Oh yea, and the audience would be encourage to light up
too during the "song" sections.
(See link for how all songs would be performed.)
