Warren Buffett is singing and playing ukulele again in public.
He did a duet of "The Glory of Love" with Jon Bon Jovi at the Forbes 400 Summit on Philanthropy in New York on Tuesday.
The song was originated by Benny Goodman in 1936 and popularized again by Bette Midler in 1988.
Here's the clip posted by Forbes.
It's planning to report on the gathering itself in the fall, but made the video available now since the "whimsical moment won't wait (mostly because of a plethora of camera phone.)"
Before they start the music, the Berkshire Hathaway CEO jokingly warns the audience that "this has been described as a once in a lifetime experience, and you'll understand why. Once will be enough."
While they may not share the same level of musical talent, Bon Jovi and Buffett both have a great interest in philanthropy.
Last year, Bon Jovi was the top name on Forbes' list of the "most charitable celebrities."
Buffett has
pledged almost all
his personal fortune to the Bill Gates Foundation,
urges other billionaires
to pledge half their fortunes, and
Lack of singing talent hasn't stopped Buffett before.
In its January celebration of the Lunar New Year, a Chinese television network played a tape of him singing "I've Been Working on the Railroad."
In April, he marked Berkshire Hathaway's purchase of the Omaha World-Herald by singing "I'm Only a Paperboy" to the tune of 1933's "It's Only a Paper Moon" while tossing rolled up newspapers at the Omaha Press Club Show.
And back in 2010, Buffett rocked out as an Axl Rose lookalike in a music video featuring GEICO associates singing a guitar ballad about the insurer's "outstanding" customer service.
And if you're wondering, while Warren Buffett and musician Jimmy Buffett are friends, both play stringed musical instruments, and long thought a family relationship was possible, DNA analysis has determined they are not related.
