Country fans who saw Randy Houser live over the weekend may have noticed another familiar face onstage. The Big Bang Theory and Roseanne actor Johnny Galecki stood in as drummer for Houser's set at Taste of Country Lansing on Friday night (June 9) and Taste of Country Buffalo on Saturday night (June 10).

Galecki plays Dr. Leonard Hofstadter on The Big Bang Theory now and is well-known for his role as David Healy on Roseanne. In clips posted to Instagram, the actor shared snippet of his time drumming for Houser at the Michigan and New York state shows.

"What playing to 26,000 (!!!) beautiful people looked like in Buffalo, NY last night!" Galecki writes. "An absolute BLAST!" In another clip, he shared the drum kit with Houser's permanent drummer, rocking out to a new song called "You Should Be Mine."

This was far from the actor's introduction to country music, however, as he was also a presenter at the 2017 CMT Music Awards on June 7 and has previously shared the stage with Houser. According to Rolling Stone, the singer and actor took part in a free concert in Santa Margarita, Calif., after the Pozo Stampede was canceled.

"I know the fans planned to camp out, have their weekend, and I know what it's like when plans are canceled and all of a sudden you don't have something to do," Houser told the Tribune of San Luis Obispo. "I felt they deserved better than that."

Houser, meanwhile, is set to play Country Jam 2017, which will be held June 15-18 at the Jam Ranch outside of Grand Junction, Colo.
