Here is another you tube (no video, but the music is much, much, clearer :)

By the way, I too remember seeing this commercial so many years ago. However, being only about 10 in 1969, and not knowing much Irish music, I thought it was based on something like "Bringing in the Sheaves" or "Rambling Wreck from Georgia Tech", lol.

Just love the song, and hearing it now kind of brings tears to me eyes. Also, enven though the images in the video aren't from the commercial, seeing images of how huge ships like ULCC's roll in the seas truly relates the power of the oceans!
