The frontman of the recently reformed BLACK FLAG was reportedly fired whilst onstage, during a show in Australia.

BLACK FLAG released their first new material since 1985's 'In My Head', an album entitled 'What The…', earlier this month.

Singer Ron Reyes has now announced that he has left the band, writing in a Facebook post that has since been deleted (via Exclaim) that during a recent show in Australia, skateboarder Mike Vallely - who sang with the band at a 2003 reunion show - took the microphone from him and asked him to leave before finishing the set for him.

"On November 24th 2013 the last night of the Australian Hits and Pits tour with two songs left in the set Mike V comes on stage stares me down, takes my mic and says "You're done, party's over get off it's over...," wrote Reyes.

Reyes added that it was a "relief", stating that he hadn't been seeing eye to eye with the band's co-founder Greg Ginn and that he wanted to make amends with Flag, the other current incarnation of the seminal hardcore band.

He wrote: "From the beginning I was happy for them and fully supported and understood why they would want to rock those songs and have a good time with friends and family. Yes I questioned their use of the name and logo but in no way questiond [sic] their motivation or right to do their thing. I envy them for they have succeeded in ways that were never possible with "Black Flag". And once again for the record, I agreed to do Black Flag before I knew there was a Flag."

BLACK FLAG consists of other original co-founders, singer Keith Morris and bassist Chuck Dukowski, as well drummer Bill Stevenson and Stephen Egerton of Descendents.

BLACK FLAG is Ginn and drummer Gregory Moore and Reyes says that Mike Vallely will likely take over as the new singer of the band.
