FM at 21

[chazlightyear]

I feel a little cheeky for asking this as i realise it's probably been asked before but i'm wondering if the FM at 21 doc and/or a doc. which i think is called the Story of fleetwood mac are available anywhere. i've been thinking about them since i found a clip of the 'Oh Diane' performance on youtube yesterday.
I'd be very grateful for any information:)
