The popular Friars exhibition at the county museum has grown organically since it opened, with new exhibits continually added.
Now three special events are to be held to mark the success of the exhibition which has been running since March.
The first event, The David Bowie Years, being held tomorrow, Thursday, is sold out.
But tickets went on sale yesterday, Tuesday, for the Edgar Broughton Years event to be held on June 24
Special guests will include Edgar Broughton, Steve Broughton and Arthur Grant who together are the Edgar Broughton Band and first played Friars in July 1969 just one month after the club opened.
The evening will include a free glass of wine or soft drink, a presentation and a question and answer session with Edgar Broughton chaired by David Stopps.
Tickets cost £10 and are available from the museum Tuesday to Saturday 10am-5pm or by telephone on 0844 870 0000 (booking fee applies).
The final special event will be held on the last day of the exhibition on Sunday July 2 from 10am to 5pm. The museum is usually closed on Sundays but will open specially to mark the success of the exhibition.
David Stopps and other Friars experts will give several guided tours of the exhibition and will be on hand to answer questions and exhange memories.
Until the final special day the exhibition is open from Tuesdays to Saturdays 10am to 5pm.
