A musician walking around SF comes across a club where the owner is
putting up
the names on the marquee.
"What's going on?" the musician asks.
"New jazz club," says the owner. "I've got Ray Brown on bass."
"THE Ray Brown?" The musician can't believe it.
"Well, not exactly. He plays like Ray and that's his name."
"Who's on drums?"
"Elvin Jones."
"Really?  THE Elvin Jones?"
"Well, not exactly. But he plays a lot like Elvin and that's what
everybody
calls him."
"Wow,"  says the musician.  "Piano?"
"Chick Corea," says the club owner.
"You're kidding? THE ONE AND ONLY Chick Corea?"
"Well not exactly, but he plays just like him.
"Cool," the musician says."With a rhythm section like that, who's
playing
horn?"
"Kenny G."
"Oh you're kidding, the REAL Kenny G?"
"Unfortunately, yes," says the club owner.
