Setting the Brüel session right

I reported my doubts about the date in my footnote to 53-09. Three jam sessions in the Shell building: The first two with Gullin and Brüel. But on the October 1952 meeting, Rolf Berg played guitar. No guitar is heard on the published excerpt.
That leaves us with a most likely candidate: 26 January 1953 with Leif Asp and Sven Bollhem in the rhythm section.
The third candidate (19 May) is the least credible. Certainly even a small notice in OJ would have mentioned the presence of the two baritone stars!
The editor of the Swedish Jazz Discography on line, Göran Eriksson, called me the other day and strongly advocated that this is the correct information:
Shell Building, Stockholm, 26 January 1953
