jams as that crazy diamond. Where does that come from?

Actually, TGRB, it comes from one of the greatest bands of all time,
Pink Flyod.

They started with a band leader and song writer who was thought to be at the time, destined to be one of the great song writers of all time, Sid Barrett.
It was a time of experimentation. Seems Sid was one of those people whose experiments would turn on him. In any case, he was a lyrical genius.

Then one day his genius vanished. The rest of the band noticed it when he came into the the studio and the glint from his eye was no longer there. they carried him for over a year, but when doing a concert he sat with them for over two and a half hours and never strummed a chord, they had to finally tell him it was over.

He left and hasn't been seen since.

A couple of years later they dedicated an album to him. Whenever they do a concert tour they start every concert with a beautiful Beethoven like twenty three minute song dedicated to him.

"Remember when you were young,
you shone like the Sun,
Shine on you crazy diamond."

They really miss him.
