AC/DC may soon announce their retirement, it was claimed on a Perth radio station. A person who was only called as “Thunderstruck” claimed that the Australian hard rock band would retire because one of the members is “quite ill.”

Radio station 6PR read an anonymous email from “Thunderstruck” on Tuesday, saying that the Rock and Roll Hall of Famers are set to retire after more than four decades of taking the stage.

“I have extremely good contacts in Europe that are very close to AC/DC. I have it on very good authority that one of the band members is quite ill and has returned to Australia with his family,” the email reads.

“AC/DC members have previously made a pact that no band members will be replaced should someone need to leave the band. No more is currently being said, however the particularly ill member of AC/DC’s son has stated that AC/DC may well be over.”

The ill member is reportedly guitarist Malcolm Young.

The station’s entertainment reporter, Peter Ford, added that the band may not “actually retire as such,” but they may just never perform or record again.

AC/DC singer Brian Johnson revealed to a Florida radio station in February that one of their members was ill, but that they still had plans to go back in the studio in May in Vancouver.

“One of our boys was pretty ill, so we didn’t like to say anything, and we’re very private about things like this, so we didn’t wanna say anything,” he said.

“But I think we’ll be going in the studio in May in Vancouver, which means we should be getting ready.”

AC/DC was formed by brothers Malcolm and Angus Young in 1973. They released their first album “High Voltage” in Australia in 1975, and made it international by the following year.

After their frontman Bon Scot died in 1980, the band briefly considered quitting. Soon, they decided to hire Brian Johnson to replace their fallen member.

The current members include the Young brothers Angus and Malcolm, Johnson, Phil Rudd, and Cliff Williams.
