Leslie Weinstein was ticked.

The 10-year-old boy had been excited to be in the audience for "The Jackie Gleason Show," for which the boy's uncle, Will Glickman, wrote; but then he found out that Gleason wouldn't be appearing that night. Tommy and Jimmy Dorsey would be subbing for him.

"I was really pissed off," he said.

But the boy, accompanied by his grandmother, went to the show anyway. Good thing he did: Elvis Presley was appearing. It was 1955 and Presley was just starting the ascent from "Heartbreak Hotel" to the King of Rock 'n' Roll.

"I started wanting to play guitar," said Weinstein, who is better known as Leslie West, the guitarist for the rock band Mountain, which plays Saturday at Ohio Thunder Valley Bike Weekend on Yankee Lake's outdoor stage.
