British ticketing services company See Tickets is offering a chance to AC/DC fans who bought tickets for the band's June 4 concert at London Olympic Stadium to get their money back.

The show is one of twelve European dates AC/DC will perform with GUNS N' ROSES frontman Axl Rose on lead vocals after Brian Johnson was ordered to stop touring or risk going deaf.

See Tickets sent out an e-mail earlier today to everyone who bought tickets to the London gig using the service. The message reads: "You have the opportunity to request a refund of your ticket. Refunds will be available from now until 5pm on Friday, May 6."

It is not presently clear if the refund offer will be made available for the other dates on AC/DC's European tour, which kicks off on May 7 in Lisbon, Portugal and runs through June 12 in Aarhus, Denmark. Following that, Rose will head out on his previously announced summer reunion tour with GUNS N' ROSES, dubbed "Not In This Lifetime". AC/DC's ten postponed U.S. dates will take place later in the year, also with Rose as frontman.

According to a Billboard.com source, Rose initially met with AC/DC members in Miami and Atlanta back in March. It was then that the decision was made to have Rose join AC/DC on tour. There was also talk of having other singers alternate with Rose, including ex-SKID ROW frontman Sebastian Bach and Nic Cester of the Australian band JET.

Fan reaction to Rose replacing Johnson — even temporarily — has been largely negative. The fan site AC/DC Italia announced it was shutting down in protest, while AC/DC biographer Jesse Fink called it "the worst decision AC/DC has ever made. Fans are pretty disgusted... AC/DC is all about the money now."

AC/DC guitarist Angus Young made a guest appearance with GUNS N' ROSES at the Coachella festival in California earlier in the month, to tie in with the official confirmation of Rose's involvement.
