Based on two dopeheads, this 1978 movie is a quintessential riot. These two amateur rock-musician guys, (Pedro De Pacas [Cheech Marin] and Anthony 'Man' Stillman [Tommy Chong]) are on a roadtrip, stoned all the time. The movie has real funny comic points, such as the story about dog eating the weed and then these guys smoking dog's shit. But to top it all, the soundtrack is wow!! Lost Due to Incompetence (Theme for a Big Green Van) by Yesca is incredible. And it was impossible to find it on Net before Roman Corrales agreed to upload the mp3 for me. This track combined with Low Rider(War) and Earache my Eye(featuring Alice Bowie) just makes for the heady mixture of music and dope!!
