Rockers Mötley Crüe are rumoured to be playing a secret gig in an intimate Camden club the night before their Wembley Stadium show.

The Californian heavy metal band posted a cryptic flyer on social media about a band called DÖGS OF WAR playing at The Underworld in Camden High Street on Friday (June 30).

Although they haven't yet confirmed the show - to an audience of just 450 - the band have been in the studio in recent months recording new tracks with producer Bob Rock, including a song called Dogs of War.

Since forming in Hollywood in 1981, Mötley Crüe have sold 100 million albums worldwide and are famed for their eye-popping stadium gigs with pyrotechnics and flame-thrower guitars.

The current line-up - bassist Nikki Sixx, drummer Tommy Lee, guitarist John 5 and vocalist Vince Lee - appear alongside Def Leppard in front of 90,000 fans at Wembley on July 1.

They will then wrap up the European leg of The World Tour on July 6 in Glasgow before heading back to the US for more stadium shows then touring Japan and Australia later in the year.

Tickets for DÖGS OF WAR's Camden Underworld gig have sold out but you can join the waiting list.
