These come from a series of 80s live recordings issued on CD as "Donovan Rising" and a second fuller 2CD set "Rising again."

They are legit authorised relases and featue a tight jazzy acc, in addition to Danny Thomson on Bass on some tracks.

The first CD Rising has been subject to many budget releases with titles such as "Donovan in Concert", and sometimes has a couple of tracks removed.
It includes a good cross section of re-recordings of Donovan's writing over the years, and some trad/blues songs. (Lang a-growing/Stealin').

Well worth a listen, IMHO
