In this week's episode, Barney Hoskyns and Mark Pringle are joined by Chris Campion all the way from Pioneertown, California. The subject of Chris' upcoming book, John Phillips of the Mamas and the Papas, leads into a wide-ranging and discursive conversation about L.A. in the '60s and the music and madness of Arthur Lee and Charles Manson.

Continuing the Southern California theme, the three men hear excerpts from a 1993 audio interview with the late Elliot Roberts in which the legendary manager talks about his client Joni Mitchell's house, the Eagles, and the impact of cocaine on the L.A. scene.

Finally, in the archive highlights section, Mark selects an interview with Keith Richards' mother, a live review of Jimi Hendrix playing London's Bag O'Nails club in 1967 and – returning to the L.A. theme – a 1972 interview with Elliot Roberts' managerial/Asylum Records partner David Geffen.
