Regarding Transition TRLP-8. My suspicion is that the session consisted of only 3 songs and was never released. "Train's Strain" was issued on TRLP-30. All three including "High Step" and "Nixon, Dixon and Yates Blues" were issued on the Paul Chambers Mosaic Select #5. It is possible that there were additional songs but I doubt it. According to my Transition LP discography the session was on April 20, 1955. The Chambers Select shows a date of April 20, 1956, which is probably a typo..
