This is Fleetwood Mac's fourth single mixed in glorious mono. Original release date is Jan '69 and it was recorded in Oct '68.
This one is a DEDICATED mono-mix, which is great to hear! But, since there are no vocals it is a bit tough to tell. . .It sounds like the lead guitar is mixed softer, and the mixing is slower. . .whatever this is the way it was heard when it went to #1 in the U.K. in Feb. '69
