I know it's not relevant but try listening to Ian MacDonald's "Maid of Islay".
It's a song about of the boat of the same name which used to come into Stornoway on the Isle of Lewis.
It's Ian's own song and on his first album on the Greentrax label:
It's a great song.
Incidently, Donovan used to live here on the Island of Skye in the late 60's. Perhaps life was such then that he wasn't sure which island he was on!
