Query: A great concert

The folks who had reservations and/or strong criticisms of this DVD, especially of Susan Marshall's performances, should just defrost their hearts. Everyone involved in the DVD played and sang their hearts out. Some of the performances were extraordinary for sure: Al Perkins' steel on every song, James Burton's Tele playing, Raul Malos' singing and the manic but totally appropriate lead playing of Dwight Yoakam's guitar player to name a few. All the "big stars" rose to the occaision. The concert rocked from the first note to the last. What more do ya want if you love Gram Parsons?
