On my holidays this year, driving around the (incredibly beautiful and luckily sunny) Yorkshire dales, I played TCH and especially Dayvan Cowboy, to death, to the point where my two year old son recognises it instantly (I have all Bob Dylan's and Simon and Garfunkel songs imprinted on my brain from car journeys as a kid).
It never fails to lift my mood. I still think it's their best, although I don't tend to distinguish between BOC songs within albums - one of their strengths is maintaining such a consistent (and each time different) mood across each album.
I completely get the posts made recently about folks' reappreciation (is that a word?) of TCH.
The first BOC album I bought was Geogaddi, by the way.
