There are several different versions of this recording and this one is the best sounding - although still rather rough sound quality.
The source for the first 2 songs is the common vinyl bootleg (which has better sound quality than most CD bootlegs). The remaining tracks are from a Dutch radio broadcast (including the intro, which was moved ahead of the bootleg tracks) from circa 1969.
