All the feels! It's been 20 years since Hootie & the Blowfish made it big, but they're still incredible live, which was evident when they appeared on the Late Show with David Letterman on Thursday, April 30. Throwing Us back to the '90s, the band performed their 1994 hit "Hold My Hand."

"The song that started it all," Letterman said, introducing the rock band, which singer Darius Rucker, Mark Bryan, Dean Felber, and Jim Sonefeld formed at the University of South Carolina in 1986. Some of their other classics include "Only Wanna Be With You," "Time," "Let Her Cry," and "Hey, Hey, What Can I Do."

After selling more than 21 million albums in the U.S., they went on hiatus in 2008 so Rucker could kickstart a solo country career.

Hootie & the Blowfish still remember their roots, though, and reunite often for a good cause. This summer, the longtime friends will come together once more in Charleston, South Carolina, from Aug. 7 to 8 for their annual Homegrown Concert. Created in 2000, the concert supports public education and philanthropy issues, and raises money for hundreds of organizations worldwide.
