The worst kept secret in rock has been revealed – Axl Rose is joining AC/DC for the remainder of their tour, taking in the Olympic Stadium on June 4.

The reformed Guns N’ Roses took to the stage at the Coachella festival in California with the rumour already confirmed.

Rose replaces Brian Johnson starting on May through to the conclusion of the Rock or Bust tour in Denmark on June 12. A question mark had been hanging over the Stadium gig – the first major concert at the re-configured venue , ever since AC/DC lead singer Brian Johnson was forced to quit touring with immediate effect – or face the prospect of going deaf.

Dates lost after the announcement will also be re-scheduled, featuring Rose.

The Olympic Stadium is set to be West Ham's new home from 2016.

A statement on AC/DC’s website said: “Band members would like to thank Brian Johnson for his contributions and dedication to the band throughout the years. We wish him all the best with his hearing issues and future ventures.

“As much as we want this tour to end as it started, we understand, respect and support Brian’s decision to stop touring and save his hearing.

“We are dedicated to fulfilling the remainder of our touring commitments to everyone that has supported us over the years, and are fortunate that Axl Rose has kindly offered his support to help us fulfill this commitment.

“AC/DC will resume their Rock Or Bust World Tour with Axl Rose joining on vocals. Following this European run of dates with AC/DC, Axl Rose will head out on his Guns N Roses, Not In This Lifetime Summer Stadium Tour.”
