Those guys are part of Lyle Lovett's acoustic band who are on tour. The Bass player, Leland Sklar usually films the concert houses they play as they jump from place to place. Yesterday he filmed them doing a sound check. They started the tour in Texas and went east. I believe that was taken in Clearwater Florida.^^^Not bad. I like groups like that that play real Texas music. As the old saying goes, "you've gotta have a fiddle to play in a Texas band."
