Just lost my post, but the Bud Shank (two PacJazz albums with Babasin/Harte) is on the Brazilliance discs! The 1954 material, I mean. Except that the CD (Brazilliance Vol. 1, CDP 7963392, 1991) gives the year of both the April (15th and 22nd) sessions as 1953 (15 tracks all in all, including the alternate take of "Speak Low")
Brazilliance Vol. 2 (CDP 7961022, 1991) has the 1958 material that came out under Shanks's name as "Holiday in Brazil" (WP 1259) and "Latin Contrasts" (WP 1281), all from March 1958.
