I've looked on Spotify and found 35 tracks for free listening in good sound,
including the 1961 Folkways LP with Rolf Cahn; "2nd Row, Third Row" (Poppy
Records 1972, backing musicians include Paul Butterfield and Garth Hudson)
and "Living on the Trail" (2002)
With Spotify everything is free, 160kbps Oog Vorbi, with a short ad lasting
about 20 seconds about once every half hour; for ten quid a month you get
the music free of ads at 320 kbps.
I'm grateful to Levinson for raising this topic because I've ordered the CD
of the Dick Farina/Rick Von Schmidt record and listened to the three discs
on Spotify. Presumably the 1961 Folkways LP with Cahn (which is good) is
available as Flac from LOC, for a consideration.
