Last week's deadline prevented getting in the news about the jam session at the Hotel Bradford this past Sunday. (It was half good and half bad.) Assets: Coleman Hawkin's superb tenoring, the tremendous drive of Pete Brown's alto, and J. C. Higginbotham's tromboning. Debits poor acoustics which murdered the ensembles, and Red Allen's attempts to be entertaining and run the whole show. Another session will be held soon, and we promise to let you know this time.

Meanwhile, Duke Ellington has opened at the RKO Boston and needs no recommendation to his devotees. He has a now singer named Betty Roche (pronounced Roshay), who should develop into a fine singer as soon as she's assimilated a little more of that Ellington elegance.

Bill Davison is more of a must item than ever at the Ken, just beyond the Met Theater, but a weekday night the preferable if you want to listen to the music. (The weekend crowd encourages too much the five shabby showgirls and the tired routines of Russ Howard, comic.

Louis Armstrong is at the Tic Toc, opposite the Met, until-Saturday, but we'd advise listening to his nightly programs on WHDH first. Lionel Hampton opens Sunday, but again the radio is definitely handier and cheaper.
