The song you're looking for is Beyond The Sea, originally by Bobby Darin. I'm not entirely sure which version was used in the commercial, but I think it's the Robbie Williams one that I've linked to below.
Lyrics to Beyond The Sea Somewhere beyond the sea
Somewhere waiting for me
My lover stands on golden sands
And watches the ships that go sailing
Somewhere beyond the sea
She's there watching for me
If I could fly like birds on high
Then straight to her arms I'd go sailing
It's far beyond the stars, It's near beyond the moon I know beyond a doubt My heart will lead me there soon We'll meet beyond the shore We'll kiss just like before Happy we will be beyond the sea And never again I'll go sailing I know beyond a doubt My heart will lead me there soon We'll meet, I know we'll meet beyond the shore We'll kiss just as before Happy we will be beyond the sea And never again I'll go sailing No more sailing So long, sailing, sailing, no more sailing Good-bye, farewell my friend, no more sailing So long sailing, no more sailing No more, farewell... No more sailing
