Hollywood actor Ryan Adams was joined by friend and keen guitarist Johnny Depp on-stage in London on Thursday night (September 18, 2014). The Hollywood actor joined the singer-songwriter for an encore at Shepherd's Bush Empire, playing a cover of Danzig's 'Mother' and Adams' new track, 'Kim'.

The pair are known to be fairly close and Depp appears on the B-side for Ryan's new single 'Gimmie Something Good', playing guitar and soloing on 'Aching For More'. 

"There was one night when Bob Mould was in town, and Johnny [Depp], my friend, the actor, and we jammed - we had this amazing jam that had to have lasted nine hours. We met in the afternoon and it lasted until 3 am," Adams told the Wall Street Journal, "Johnny was playing bass for some of it, I played the bass for some of it - we're basically Die Kreuzen right now, by way of Minneapolis, by way of Los Angeles. Total, otherwordly weird jams."

The set - as part of a short UK tour in support of Adams' new self-titled album - was heavy on the country-tinged Cardinals tracks, though featured plenty of the new songs, as well as tracks from this year's surprise punk release 1984.
