Only 15 minutes, alas, but well worth catching - Joan Armatrading features the folk-rock songwriter-singer-guitarist Richard Thompson in the third of five programmes she is doing about guitar luminaries.

It went out on BBC Radio 4 this lunchtime but is available on demand HERE for the next seven days. (May not be available outside UK.) The preceding programme, featuring Sharon Isbin, is still available for five more days for anyone interested in classical guitar.
