Vol. 4 : « Voyajologie »

This is the first of three versions of this LP (B&W/Green back cover) Back cover variant 1: Black & White with green text Back cover variant 2: Black & White only (no green text) Back cover variant 3: Black & White only. Instead of the group photo, this version uses the three separate photos (as used in later volumes in the series) along with promoting volumes 1, 2, 3, 5, 6 and the Beethoven album. (Which would make this a 1972 release, or later) The discs for variants 1&2 are identical.
