collector's piece

I found this original 78 rpm 12 inch record among others in a charity shop in Boston, UK. It's "St Louis Blues" by Bing Crosby with the Duke Ellington Orchestra and the cover registers that it was recorded in New York on 11th February 1932. The record itself is in a neat cardboard sleeve on which the previous owner had bothered to list all musicians:

Arthur Whetsol, "Cootie" Williams, Freddy Jenkins (tpts). Joe Nanton, Lawrence Brown (tmbs), Johnny Hodges (alto, sop) Harry Carney (bar, alto, clt), Barney Bigard (clt, ten) Duke Ellington (pno), Fred Guy (bjo, gtr) Wellman Braud (bs), Sonny Greer (dms) Bing Crosby vocal.
On the label (Columbia DX898 BX 11263) I'm told that the composer was Handy and in parenthesis that it's a "concert version. On the obverse is "Creole Love Call," again a concert version (Columbia DX898 BX 11264) with the same recording data as Side 1.

Obviously the previous owner was not only a keen jazz fan, but a person who understood the true essence of jazz listening. What genuine aficionado can truly enjoy a piece of music without knowing the names of musicians, and where and when it was recorded? This one has gone to great lengths to organise his or her record collection, taking pride in identifying the line-up on every record probably so each soloist can be identified in turn. I imagine him or her sitting in a dusty arm-chair beside a battered old record player, ear cocked towards the speaker as he or she (I desperately try not to be sexist) holds the record and reads the notes and silently applauds in sincere appreciation. Or maybe it's not imagination - it's a mirror.

Yet how did this collection end up in a charity shop? Once a jazz fan always a jazz fan. They don't sell records or books; they store them for future reference. I'll never know why, but I can guess.
