A very rare concert poster advertising The Aquae Sulis Incident, a May 1970 concert in Bath, England headlined by Fleetwood Mac.  Conflicting online sources cite this as the last, or second to last show Peter Green played before leaving the band he founded.

Aquae Sulis refers to the ancient Roman city of Bath, known for an impressive and complex bath-house built around natural hot springs, dedicated to the goddess Sulis Minerva.

The concert also featured Chicken Shack, subbing for the advertised Soft Machine, Juicy Lucy, Sam Apple Pie, Matthew’s Southern Comfort, Quintessence, Wishbone Ash, and others.

The poster is silkscreened in black and silver metallic ink, on thin stock.  It is in overall excellent condition, rolled, with minor creasing (less than appears in the image here) and tiny pinholes in the top and lower right corners.  There is a tiny chip to the lower left corner, about the size of a match head.  19 ¾” x 29 ¾”.

The only example we’ve seen of this rare poster.

From the UK Rock Festivals website: A smallish crowd gathered to see this one, which is presumably why the exercise was not repeated… Apparently Fleetwood Mac played past the curfew and the power was terminated…but when the power was turned off on him, Mick Fleetwood kept on playing! …Not only was this probably one of the most exotically named festivals of the 1970s, but this was also the last but one show which Peter Green played with Fleetwood Mac.

From Wikipedia: In April, Green decided to quit the band after the completion of their European tour. His last show with Fleetwood Mac was on 20 [actually 23] May 1970. During that show the band went past their allotted time and the power was shut off, although Mick Fleetwood kept drumming…In 1971, he had a brief reunion with Fleetwood Mac, helping them to complete a U.S. tour after guitarist Jeremy Spencer had left the group…

The Facebook page RockHistory also cites this as the final show Green played before leaving Fleetwood Mac.  One other online source claims Green also appeared with the band at the Roundhouse in London on May 28, but we can find no other confirmation of that claim.
