The Last Sweet Days of Isaac is an American Off-Broadway rock musical by Gretchen Cryer and Nancy Ford, which premiered in 1970.

Isaac Bernstein (Pendleton) imagines himself at the brink of an untimely death, and determines to make every subsequent moment a perfect work of art.

During the hour they are stuck there, Isaac attempts to teach Ingrid his life philosophy.

They attempt to make love to each other's image, when a newscast interrupts their tryst with a report of Isaac's death at a demonstration.

Noted theatre critic Walter Kerr called it "My favorite rock musical".
