There should not be any argument on this one.
Southern Cross by Crosby Stills and Nash
Actually, Wooden Ships is also a good choice.
How could there be a debate at your house on this? What, someone in your family is suggesting row, row your boat?
It’s not a heated debate. Some like the Sloop John B. Some think Southern Cross is better. It’s not cut and dried. I love both songs but if I could only hear one before a final voyage - Southern Cross takes it in a photo finish...
