I'll check with a few old ex P&O shipmates, they might know something. While we're on the subject, does anyone know a song that begins, "While I was a walking down old KG5 a Shaw Saville Liner I happened to spy". Same air as "6 miles from Bangor to Donaghadee" etc.
A shipmate of mine used to sing it back in the 60s. I haven't seen him or heard the song since.
