Despite a cold, superstar singer/songwriter Joni Mitchell is a most obliging interviewee for music show host Richard Driver. Having adopted a number of styles over the years, she says she has become a “neither/nor”: no longer easily categorised by radio as a jazz or a rock musician. She performs compelling acoustic versions of ‘Number One’ (from her then current album Chalk Mark in a Rain Storm) and the brand new ‘Night Ride Home’ which she doesn’t know how she’ll record. It would show up in a similar arrangement as the title track of her next album.
