No ship sailing

Echoes of the Broadway Everglades,
With her mythical madonnas still walking in their shades:
Lenny Bruce, declares a truce and plays his other hand.
Marshall McLuhan, casual viewin', head buried in the sand.
Sirens on the rooftops wailing,
but there's no ship sailing.
Groucho, with his movies trailing,
stands alone with his punchline failing.
(Genesis, Broadway Melody of 1974, 1974)
