Fourteen months after Brian Johnson was nearly forced into a premature retirement due to a hearing impairment, the AC/DC singer returned to the stage Sunday night. Johnson joined fellow special guest Robert Plant at Bad Company singer Paul Rodgers’ concert in Oxford, England.

Last June, Johnson shared some positive news regarding his hearing after meeting with an in-ear technology specialist. “I was really moved and amazed to be able to hear music again like I haven’t heard for several years now,” Johnson said at the time. It’s unclear whether Johnson’s return to the stage was a result of that in-ear technology.
