In celebration of famed English photographer Denis O'Regan turning 69 years old, the West Contemporary gallery is opening a digital exhibition to celebrate the legendary music photography O'Regan has accomplished over the years.

The exhibit features never-before-seen pictures of superstars such as David Bowie, Mick Jagger and Freddie Mercury in their musical prime.

The 69 days exhibit will deliver a selection of O'Regan's classic pictures along with limited-edition prints. 1o per cent of all sales will be donated to London's Great Ormond Street Hospital's charity (GOSH). O'Regan's exhibit will run from October 24 until January 1, 2023.

Among the unseen photos is a shot of Mick Jagger stretching in preparation to perform at Slane Castle. The rockstar is wearing matching red and white striped pants and a jacket that spells out 'MICK' in large white lettering.

There are also multiple photos of Bowie, who was a long time collaborator with O'Regan. One photo finds the glam rock star relaxing behind a pair of sunglasses outside Palm Springs, California in 1983 during Bowie's performance at the Apple founder's US Festival in San Bernadino. Another shot depicts Bowie enjoying the Australian sun in Melbourne at VLF Park.

Bowie passed from liver cancer on January 10th, 2016 after turning 69.

The exhibit also features a collection of images picturing the late Freddie Mercury, frontman of legendary rock band Queen. One image finds the icon unwinding on the terrance of his Budapest penthouse suite in 1986 while he rehearsed lyrics to a local folk song that Queen would perform later that night in Hungary's Nepstadion stadium.

O'Regan also captures Mercury in all his glory on stage during the 1986 Magic Tour, with shows at Slane Castle as well as Wembley Stadium and Maine Road.

Mercury passed in November 1991 from bronchial pneumonia resulting from AIDS at the age of 45.

Other photographs completing O'Regan's exhibit includes Mick Jagger performing at the Ullevi Stadium in Gothenburg, Sweden in 1982 with the Rolling Stones, a closeup of guitarist and songwriter Kieth Richards of the Rolling Stones, and images of Bob Marley in Montego Bay in 1980. O'Regan also captures a heartwarming shot of Bowie and Mick Jagger laughing together in London.

During the exhibition, there will be ten limited edition prints of each photo that will be for sale, ranging from £1,440 to £9,000.

"We at GOSH Charity are honoured to be part of this fantastic project which will raise funds to support the hospital's most urgent needs," said GOSH Charity's deputy director of relationship funding Sarah Bissell.

"Money from the sale of each print could fund ground-breaking research into children's health, support services, for children and their families, vital rebuilding and refurbishment of the hospital and life-saving medical equipment.

"I'd like to extend a huge thank you to Denis O'Regan and West Contemporary Editions."

Denis O'Regan's exhibition and special edition print sale, 69 DAYS, begins October 24 and will run through January 1 2023.
