I like Alan Yentob as a presenter and don't see what his lack of in depth knowledge has to do with his ability to get others to impart their expertise. I found the programme both entertaining and informative and I enjoyed particularly the clips of Segovia, Django Reinhardt and the US guitar workshop.

The BBC still commission excellent documentary series (David Attenborough's programmes, for example) and I think that some of the criticsm on here is unfounded.
