It's a very short interview, I guess she's just there to promote the album and a FM tour is mentioned. He initially points out that it's really most of Fleetwood Mac are on this duet record, and then they play some of IMW with video clips of Lindsey and Christine in the recording studio. Maybe someone can post the clip? She says very little, but good to see her on the show.
edit...if anyone in the UK wants to see it - she was on around 13mins (I think you have to be in the UK to use iplayer although not sure??)
