Stokke was TNT's live keyboardist from April 1987 to 2011 and played on every TNT album from Realized Fantasies (1992) to A Farewell to Arms (2010). However, he was never a permanent TNT member. "I'm cool with my position in TNT," he said in a 2010 interview, "Some people ask me why I'm not in the pictures and why I'm not profiled. That's just the way it is, and I'm completely laidback with that. I got to experience the rockstar existence so much in 1987 and especially in 1989 and a little bit into 1992, so that dream has been realized. If I'm not upfront, that's totally cool, because I know I've been a part of all this." He played his last concert with TNT in Umeå, Sweden on March 5, 2011.
In January 2011 he found out he had cancer. Stokke died on April 27, 2011 at the age of 44. He is survived by a son.
