Comic duo Cheech Marin and Tommy Chong have put aside their differences to tour together for the first time in over 25 years.

Cheech & Chong: Light Up America will hit 22 cities in the US from September 12 to December 20.

Chong, 60, said: "This is a moment that I've been looking forward to for many, many years because we have such a legacy and history together that we couldn't escape it, even if we tried.

"At the end of the day we just looked at each other and said 'we better do this now man, because there ain't no tomorrow.'"

The pot smoking duo were one of the most successful comedy teams of the 1970s with hit movies and chart-topping records based on their brand of marijuana-influenced humour.

But the pair acrimoniously split up after the release of their album Get Out of My Room in 1985.

Marin, 62, said their jokes should still appeal to today's youth, as well as their older fans.

"We've had the younger audience all along. Every time they hit that certain age, they go through that Cheech & Chong period of watching the movies, listening to the records. So, it's almost like a right of passage," he said.

He joked that the pair had considered calling the show the Womb to Tomb tour, to highlight the broad age range of fans.
