METALLICA guitarist Kirk Hammett joined JUDAS PRIEST on stage last night (Sunday, September 26) at the Louder Than Life festival in Louisville, Kentucky to perform "The Green Manalishi (With The Two Pronged Crown)", a song written by Peter Green and recorded by FLEETWOOD MAC. For the performance, Kirk used his Gibson 1959 Les Paul Standard that once belonged to the immortal genius of both Green and Gary Moore — affectionately known and celebrated worldwide as "Greeny."
