In a video of the performance Bon Jovi jokes that the Berkshire Hathaway Inc. CEO may replace guitarist Richie Sambora in his band.

But Buffett told the crowd of more than 100 entrepreneurs they’d know as soon as they heard the duet that it wasn’t worth repeating.

Buffett has pledged to give away 99 percent of his fortune over time, and he has been encouraging other wealthy people to give away at least half of their fortunes.

Bon Jovi runs a foundation that helps people struggling with poverty and homelessness.

Buffett raised the hackles of New Jersey Gov. Chris Christie back in February for continuing to call on higher taxes for the wealthy.

“Cut a check and shut up, that’s what I say, okay?” Christie said in February. “I’m tired of hearing about it. He wants to pay more taxes, pay more.”
