Black Label Society guitarist Zakk Wylde is set to appear on William Shatner's forthcoming album.
Wylde is contributing guitar parts to Shatner's cover of Black Sabbath's 1970 classic Iron Man, which will be included on the Star Trek legend's follow-up to 2004's Has Been.
"Just watched tracks being laid down by Zakk," writes William in a post on Twitter. "A master playing a cover of Iron Man. He's fantastic! I'm energised."
William Shatner's new album Seeking Major Tom will be released later this year.
