Johnny Depp joins Aerosmith to play guitar on stage at Boston gig

The 51-year-old actor performed 'Trains Kept A-Rolling' with the rockers

Johnny Depp surprised Aerosmith fans on Wednesday night when he strapped on his guitar to join the US rockers for their Boston gig.

The Pirates of the Caribbean star took time off from filming Whitey Bulger biopic Black Mass to showcase his musicianship at the Xfinity Center.

Frontman Steven Tyler, from Massachusetts, introduced his high profile guest to the crowd, exclaiming: “Yo! Bringing out on stage my good friend, Mr Johnny Depp!”

The 51-year-old actor played guitar and performed an extended solo on the band’s hit song “Train Kept A-Rollin”, from their 2012 album Music From Another Dimension!.

His fiancée Amber Heard was watching the gig backstage, reports suggest.

Depp features on the studio version of “Trains Kept A-Rollin” and joined Aerosmith for a series of live shows during the year of its release.

Last month, he rocked up at Willie Nelson’s gig to play guitar with the country singer’s Family Band. 

Depp learnt guitar and started playing in garage bands after he was given the instrument by his mother aged 12.

He dropped out of high school to become a rock star before meeting Nicolas Cage who advised him to pursue an acting career.

Depp was nominated for an Oscar for his famous role as Captain Jack Sparrow in The Curse of the Black Pearl after modelling the character on The Rolling Stones guitarist Keith Richards.

He played guitar on Oasis’ “Fade-In-Out”, Shane MacGowan’s first solo album and Marilyn Manson’s Born Villain among others.
