In this week's episode, Barney Hoskyns and Mark Pringle are joined by special guest Keith Altham to pay tribute to the late Scott Walker, an artist he interviewed many times for New Musical Express. They consider Walker's early years as a teen idol and as a Walker Brother, followed by his bold '60s solo albums and his radical re-emergence in the '80s. Keith talks about touring with Scott and Jimi Hendrix – and about introducing the NME to the concept of "humour".The three of them listen to a clip from an interview with Martin Fry and Mark White of '80s icons ABC about Trevor Horn's production of debut album The Lexicon of Love. Mark then introduces selections from the week's new additions to the RBP library, including Mick Jagger talking to Dawn James in 1965, Anne Briggs "zooming down a whirlpool to annihilation", David Bowie's Ziggy Stardust album, My Bloody Valentine live at London's Clarendon, John Mellencamp's self-confessed status as a rock cliché and Salt-n-Pepa being denied their rightful place in hip-hop's history. Barney rounds it all off with tributes to writers Steven Wells and Mick Farren.Hosted by Mark Pringle and Barney HoskynsProduced by Jasper Murison-BowiePieces discussed: Keith's articles on The Walker Brothers, Scott Walker and Scott hiding away; Scott Walker by Chris Welch, Scott Walker by Ian McDonald, Scott Walker by Richard Cook, Scott Walker by Graham Reid, Mick Jagger, Anne Briggs, David Bowie's Ziggy Stardust, My Bloody Valentine @ The Clarendon, 10 Questions for John Mellencamp, Salt-N-Pepa, T.
