His influence has been acknowledged by many musicians including Jimmy Page and Robert Plant of Led Zeppelin (who named the song "Hats Off to (Roy) Harper" after him), Pete Townshend of The Who, Kate Bush, Pink Floyd (who invited him to sing guest lead vocals on their song "Have a Cigar"), and Ian Anderson of Jethro Tull; who stated Harper was his "...primary influence as an acoustic guitarist and songwriter."
More recently, Harper's influence has reached across the Atlantic and been acknowledged by Seattle-based acoustic band Fleet Foxes and Californian harpist Joanna Newsom, with whom he has also toured. Harper turned 70 in 2011 and performed a celebratory concert at London's Royal Festival Hall.
On the occasion of his 71st birthday, I have created 1600x900 Art/Wallpaper:
Happy 71st Birthday To Roy Harper - A Bit Of Groovy!
