System Of A Down frontman Serj Tankian took on a Game Of Thrones song at a recent concert in Los Angeles which saw music from the hit show performed live, NME said.

Tankian sang ‘The Rains Of Castamere’, something of a House Lannister theme, during the event. The song was recorded by The National for the Game Of Thrones OST.

The long-running HBO series will return to screens in July for the next eagerly-awaited instalment.

Meanwhile, Kit Harrington has spoken further about what fans should expect from the seventh season.

The producers have also confirmed that Ed Sheeran will make a cameo appearance in the show’s seventh season.
