Hello all, I just got a copy of Vaughan 1900, Vaughan Quartet, "Echoes From The Burning Bush" / "There Will Be Somebody Waiting." I don't see a matrix number on it. Tony Russell's Country Music discography does not cover this issue, ending with Vaughan 1850. Any ideas on matrix numbers and a recording date? Is this a post-1942 record? Gregg Kimball
