Cucoon would appear to have been a one-off Reggae label. The only Cucoon record that googling brought up was the one shown above, Jackie Bernard's 'Roots Music' (JBR-01; 1975); the JBR prefix hints that Cucoon was Bernard's own label. He was one of the founder-members of popular Reggae group The Kingstonians. Thanks to Sam Mauger for the scan and for bringing Cucoon to my attention.
