Cheech & Chong 'Light Up' additional reunion dates

Reunited stoner comic duo Cheech & Chong have added stops and a new launch date to their upcoming comeback tour, the pair's first concert trek together in more than 25 years.

Tommy Chong and Richard "Cheech" Marin will kick off the outing, now labeled "Light Up America and Canada," Sept. 5 in Ottawa. The trek, which is booked for more than 30 cities, will run through a Dec. 20 show in Denver, CO.

Chong's wife, Shelby, will open for the pair with her own standup routine. Details are below.

Cheech & Chong--who released nine comedy albums between 1972 and 1985, along with eight feature films, including the surprise 1978 box-office hit "Up in Smoke"--originally broke up in the '80s amid creative differences. Marin told the Associated Press that the pair has tried to reunite in the past, but always ended up fighting too much with each other.

"It takes about 3 minutes for that to happen. There's this veiled hatred," he said. "We've kind of resolved that. We've gotten to the age where we don't feel like fighting anymore because the end is a lot closer than the beginning."

Marin has spent most of his time since the breakup working in Hollywood and making frequent appearances in movies and television, while Chong has resumed his standup comedy career after serving eight months in prison in 2003 and 2004 for selling drug paraphernalia over the Internet.
