These two giants of 80s rock have worked together before in the studio, but this will be the first time that they've headed out on tour together. Michael McDonald has played with Steely Dan and The Doobie Brothers, co-writing their biggest hit What a Fool Believes. For the last decade he's been exploring his love of early soul with albums of Motown covers. Toto are of course best known for karaoke standard Africa, but have amassed album sales of over 35 million over the course of their career.
