There is an expensive item (£29.99) on ebay at the moment for a "very, very rare vinyl LP" which includes the two songs you've mentioned "Fernando" and "Day is Done":- Folk 77 'I Have a Dream'. The ebay listing says nothing about the singers but you could send a message to the seller to ask for more information. So far as I can see the record label is CMS .... which isn't familiar to me.
By the way if you're tempted to bid for the record check out this site first:- Sounds Travel - Vinyl LPs - Folk which is offering a copy for £8.00!
