just to add a slightly different perspective..

back in the early 70's when people my age were in their early to mid teens..

Donovan's career was loosely evaluted as divided into 3 phases.

1] The really good post 'sunshine superman' psycedelic pop-folk-rock LPs and 45s
peaking with "Gift from a Flower" double LP boxset

2] The not quite so good late 60's early 70's tax exiled 'mature earnest artist'
and post breakdown career comeback phase..
All downhill after the best tracks on "Open Road" & "Cosmic Wheels"

3] The early dated solo 'troubadour' recordings which mostly sounded a bit dull
and trite in comparison, and were devalued by association
from all the 'cash in' cheapo budget label "Golden Hour of.."
type re-releases..

But if it wasn't for Donovan, I probably wouldn't have so easily got into Pentangle..
and then start scouring local Library's for other folk artist and 'Topic' LPs..

Then a few years later as Punk rock was raging
in the big urban cities,

Steve Hillage covered "Hurdy Gurdy" man..

and all the pieces fell into place..

.. my small market town in the west country become a natural breeding ground
for adolescent 'cider and mushroom and pothead pixie' punk folk bands...
