I remember a girl singer once starting rather tentatively on the song that begins,
"My Willie sails on board the tender..."
It's one of those "Lover's Ghost" songs, and when she got to the lines, "And there she spied her Willie standing/ His two pale cheeks as white as snow" ...the singer cracked up completely and had to abandon what is in fact a very lovely song.

The Irish version of the name, by the way, is Liam.
