Johnnie Walker celebrates the 70s by playing classic tracks from both sides of the Atlantic and archive sessions. This week he speaks to Ian Anderson of Jethro Tull. They talk about why Ian decided to start playing the flute, what inspired the band to write a concept album, and Johnnie plays some Jethro Hull hits from the decade. Kate Bush is this week's music focus and for Radio Rewind Johnnie has a couple of clips of Todd Rundgren.
