Review of Let the Good Times Roll

I watched this great film back in the early 70s and loved it, can't believe that a great film like that even if it was a documentary, believe it or not i was only a teenager then for film to have had such an impact on a teenager that is a great job done. Have not seen or heard of this in some thirty six years, the way it was put really showed up all the artists, a big thank you to all involved in making this film so memorable that i can still remember some scenes of the film as if it was yesterday that i watched it. Loved Chuck Berry's Guitar playing, the song Great Balls of Fire and Fats Domino. Now i am trying to purchase this on DVD so i can add to the rest of my collection. Please can someone let me know.....
