Thanks for posting this flyfronted, I really enjoyed listening to it.
Don's choice is an interesting one - predominantly tracks that got into the charts or were written specifically for the skinhead market. Many aficionados of 'Skinhead Reggae' would turn their nose up at these today but in truth these are the tracks that people bought and listened to back in 1970/71. I note that Don Letts was born in January 1956, which made him 14 in 1970 and this is reflected in his selection - some of these tracks came out when 'skinhead' was on the wane, but would be the sound-track to his youth. I have recently been to a couple of ska nights as some people I know are in a local ska band. The night also includes a DJ playing "Ska and Skinhead Reggae" - I hardly know any of the tracks he plays. In a similar manner to Northern Soul, there seems to be a snobbishness or elitism in playing obscure stuff, whereas the reality is they would fill the dance-floor with records that people know. The tracks that people are familiar with these days tend to be those covered by Two-tone bands such as The Specials or those re-made by UB40. One of the most popular reggae tracks of 1970 was not featured by Don Letts. It was by Bob & Marcia and led to groups of white kids all over the country dancing to, "Young, Gifted and Black." A cultural melting pot indeed!
One comment I did disagree with though is that skinhead was 'the only thing' for teenagers at the time. This was certainly not my experience. When I and two class mates became skinheads in the autumn of 1969 we were the only skinheads in the school. By early 1970, when skinhead was reaching it's peak nationwide, there was still only one other lad and one girl in our year and probably less than three dozen kids in the whole school out of about 1000 pupils. We were NOT mainstream. This is reflected in record sales at the time - the Skinhead Moonstomp LP does not feature in a list of the years top selling LP's, yet Led Zeppelin spent 5 weeks at the top of the album charts in 1970, Black Sabbath also feature and "Bridge Over Troubled Water" seemed to be on Top Of The Pops every week for f#~*ing months!
Going by all my older cousins ( mid / late teens ) the main other music from Reggae was Tamla Motown and 60's soul .. those motown chartbuster LP's were at every party / youth club disco .
