My introduction to Weill concert music (e.g. beyond Mack the Knife) was playing a suite from Der Silbersee with my college orchestra. We toured it to Lincoln Center and Lotte Lenya apparently attended, though as a callow youth I didn't know who she was beyond Weill's widow. I don't know how or who funded those tours and recordings when I was in the orchestra, but I'm grateful for it.
