I think it might have been me you heard singing it. My words are fractionally different to those already posted.

Now my friends the meeting is over sisters we must part.
And if we should never meet again you'll be with me in my heart.
And we'll meet on the shore
We'll meet on the shore.
Yes we'll meet on the shore
And be friends for evermore.

Sisters becomes brothers, singers, players, drinkers or any other thing appropriate to people present.
