I first heard this record on New Years Eve at the end of 1971 in a pub just off Piccadilly Circus. No doubt the sound was enhanced by ridiculous amounts of booze but it was a record that had the whole place rocking. It has since been used and sampled by many others but this was the original which I bought the next day...
I saw Osibisa in Croydon in about 1977. We actually went to see a band called Moon who were supporting.
