AC/DC shook the Grammys stage on Sunday, performing a string of songs which included "Highway to Hell."
Lady Gaga, rock star at heart and Tony Bennett's BFF, could not contain her excitement.
Neither could Jamie Foxx.
The rockers are currently gearing up for a summer tour to promote last year's "Rock or Bust," which debuted at no. 3 on the Billboard 200 in November. The group, a seven-time nominee, was not up for awards this year, as the album was released after the eligibility period ended.
AC/DC had an eventful end to 2014, as the group's long-time drummer, Phil Rudd, was accused of "attempting to procure a murder" in November. The charge was dropped, but in an interview with HuffPost Entertainment, AC/DC guitarist Angus Young said the band had issues with Rudd before the legal trouble.
"When we were recording, it was quite difficult to just get him in the studio," Young said. "When we were in London when we were starting up to do the video shoot and stuff and it was the same then. He didn’t show, you know? That’s something we’ve got to resolve. Phil's got to sort himself out."
