Just back from a week on the north coast of Ireland, great place but terrible weather just like home. Reminded me of a song, possibly called Glenarm Bay. The song had a repeated refrain, which ended

"and the blue waves washed the pebbles white, along Glenarm Bay."

Any more words and verses? The pebbles really are white along Glenarm Bay, although the day we were there, the waves weren't blue.
