X is an album by the American comedian Y.
The phrase X , as used by Y, refers to a catastrophe of Epic proportions.
The once-upon-a-time logo of a well-known prog-rock band Z is shown in the image. [ it has been cropped a bit for obvious reasons ]
The members of Z used to be good friends with Y. The title song from one of their best-selling albums, features the same theme X.
The artwork for the album also showed the after-effects of the catastrophe.
X, Y , Z ?
Cracked by all and sundry, some even messing up the variable names in excitement.
@Hasan – thanks.
General advice from the QM – Learn to swim…
X – Arizona Bay
Y – Bill Hicks
Z – Tool
