Lost Beckett masterpiece discovered in Marsham Street

From a recently discovered Samuel Beckett notebook...

Becket identifies the players only as Rosco - a once wealthy business type in a suit; and Cloggie - a foreign gentleman, possibly Dutch?

Rosco: “Let's go."
Cloggie: "We can't."
Rosco: "Why not?"
Cloggie: "We're waiting for Wilko.”

Curtain falls slowly as they look hopefully into the wings...
