Manchester, England-born singer/songwriter Roy Harper will celebrate his 60th birthday Sunday (June 10) with an intimate, star-studded show at London's Royal Festival Hall. Harper, whose actual birthday is June 12, will be joined by former Led Zeppelin principals Robert Plant and Jimmy Page, as well as Kate Bush at the event. Harper will perform solo and with the guests during the sold-out show.

"I've invited a few guests to keep me company on the night," Harper writes in a letter to fans on his official Web site. I've wanted a special gig to celebrate the breadth of the material and the lark for some time. My birthday has given me a good excuse and it looks as though it's caught people's imaginations."

The show comes in advance of the release of a new 14-song career spanning compilation, "Hats Off," due June 19 from The Right Stuff/EMI. The set combines solo songs with many of the collaborations Harper has recorded, including "Male Chauvinist Pig Blues," with Page, late Who drummer Keith Moon, and Faces/Small Faces bassist Ronnie Lane; and "You" with Kate Bush and Pink Floyd guitarist David Gilmour. Also included on "Hats Off" are the tracks "These Fifty Years" with Jethro Tull's Ian Anderson on flute and "One Of Those Days In England (Part 1)," which featured vocals by Paul and Linda McCartney, guitar work by Ten Years After's Alvin Lee, and Lane on bass.

Harper, who toured the U.K. extensively in April and May, is planning a fall run through the region in support of the compilation, as well as his latest studio album, "The Green Man," released earlier this year in the U.K. via the Science Friction label. Those dates are scheduled to kick off Sept. 17 in Manchester and finish Oct. 7 in Coventry, with Irish dates yet to be announced.
