Twisted Sister performed at the Sweden Rock Festival in Sölvesborg, Sweden last week and were joined on stage by Lemmy Kilmister and Phil Campbell of Motorhead in a rendition of The Rolling Stones' classic tune, "It's Only Rock 'n' Roll (But I Like It)". View fan-filmed footage below. The band's 25th anniversary reissue of "Stay Hungry" is due out on June 30th on Rhino Records. The package contains all the songs on the original release, re-mastered, as well as ten demo songs that didn't make the album and have never been heard. Also included is a brand new Twisted Sister song, "30", which the band recorded recently.
