Robert G. Pettibone gives February 14, 1953 as the recording date with Bill Harris and Chubby Jackson, including the tracks C-Jam Blues, Jive At Five, Tutti-Frutti, and Sue Loves Mabel, released by Norgran EPN-7. Anyway, I'll have to add this recording.
December 14, 1952 (with a question mark) is the date given for this session in Michel Ruppli's 'The Clef/Verve Labels, A Discography' book.
Anyway welcome here, Hepcat! Will check further on this Mariano discography. He is one of my favorite players
