I just saw the tail end of that Don Letts docu! will def be watching it again on the rerun.
Don was always one of the nicest, most sensible and even-keeled guys in those days-- often in the midst of total mayhem.
And yes the reggae cross-over those days-- all the punk clubs played it, every band that could attempt that backbeat had a reggae-inspired song (the Ramones couldn't, bless 'em). And we loved the political content. This was before the homophobia became in-your-face.
When will we get to see the BBC-1 piece here, Anna-- can we get one of your Jimmys to burn a DVD for us?
