Well, isn't this interesting...

...at Deep Tracks, Sirius Ch. 16, the Grateful Dead singing the Merle Haggard classic "Mama Tried." It has a pretty good groove to it, just like the original does, though to be honest I'll always prefer the Haggard original -- and you can say that of all of Haggard's records. Merle Haggard is just the man and that's all there is to it, though there are those that can do his songs justice. (Come to think of it, George Strait nails that song pretty good too...)
