Rock band AC/DC have been forced to postpone a series of gigs after frontman Brian Johnson was warned he risks going deaf.
Doctors have told the Back In Black singer from Gateshead to “stop performing immediately” or face total hearing loss.
AC/DC, whose hits include Thunderstruck and Highway To Hell, are due to perform the first concert at London’s Olympic Stadium on June 4.
It is understood organisers expect the gig to ahead after the band said their US dates were being rearranged to later this year, with a guest vocalist likely to feature.
The band are also due to play at the Etihad Stadium in Manchester on June 9.
A statement on the group’s website said: “AC/DC are forced to reschedule the 10 upcoming dates on the US leg of their Rock or Bust world tour.
“AC/DC’s lead singer, Brian Johnson, has been advised by doctors to stop touring immediately or risk total hearing loss.”

Johnson, 68, has been lead singer with AC/DC since 1980 following the death of former frontman Bon Scott.
The postponement of gigs is the latest in a series of setbacks for the band.
Former drummer Phil Rudd pleaded guilty last year to charges of drug possession and making threats to kill. He was sentenced to eight months of home detention.
Meanwhile, in 2014 it was announced that founding member and guitarist Malcolm Young was suffering from dementia and would not be returning to the band.
