An obscure label from 1973. The only UKUA release that googling brings up is a single by Afro-Latin Jazz group Ujamaa, 'Add Up The Score'. It had a catalogue number of US-001. Ujamaa was led by prominent jazzman Lionel Grigson; it seems likely that the label would have been his. The label design was eye-catching; as yet I haven't managed to source a scan for this site but one can be seen on 45cat. Thanks to Klepsie of that site for bringing that record to my attention.
