Comment by Madame Streggae:
This was pressed umpteen times over the years in both mono and stereo - it came on light blue, yellow, pink and orange (probably the most common) WIRL labels, as well as with a yellow label heralding 'Island series'. A hugely common album and often sold us a 'souvenir' (in fact, some sleeves have this as a strapline on the front) of Barbados. My copy is handsigned by all band members, but I daresay many of them were.
The UK Island issue on the other hand is quite elusive - maybe the availability of WIRL copies hindered its sales.
