Kristian Nairn aka Hodor from HBO’s Game of Thrones has jammed backstage with Megadeth at Hellfest in France.

A video posted by Kiko Loureiro, Megadeth’s guitarist shows Nairn jamming backstage with the band. Nairn makes his way through several of the band riffs alongside Dave Mustaine.

Nairn reposted the video on his own account with a heartwarming caption. “Sometimes I don’t know how things happen. My 14-year-old and 42-year-old self-had a massive bucket list item checked off and got to play warm up with Megadeth yesterday. The band that started my journey honestly. I don’t have the words. I just don’t. Thank you”

Oh, and the gentle giant also got to introduce the band to stage. Check it out below:
