Tom Waits teases live shows?

The singer releases a pirate themed picture fuelling tour speculation

Earlier today Tom Waits released a cryptic picture, fuelling speculation that he is set to announce live shows, possibly of port cities or even aboard a boat.

The photo, pictured above and entitled Permission To Come Aboard?, sees Waits dressed as a cigar chomping pirate – complete with cutlass and eye patch – above the date August 7, on which a full announcement is expected to be made.

The eccentric singer-songwriter last toured in 2008, with the Glitter And Doom Tour, which comprised 13 shows in the United States and 15 in Europe, including two shows in Edinburgh.

Earlier this month, Tom Waits performed material from his most recent album, 2011’s ‘Bad As Me’, live for the first time. He appeared on the Late Show With David Letterman to sing ‘Chicago’, accompanied by his son Casey Waits on drums, bassist Larry Taylor, guitarist David Hidalgo, keyboardist Augie Myers and guitarist Big Bill Morganfield.

Waits also appeared on Late Night With Jimmy Fallon where he played another song from his 17th studio album, ‘Raised Right Men’. Scroll down to watch footage of both appearances.
