Have sung the song many times AND smoked a tin of the tobacco. I prefer "Balkan" style tobaccos though ;)
It's rare, in my experience, to hear a rendition of the song that isn't dressed up with stringed instruments and/or the modern German/Dutch "choir" treatment, so as an alternative I sing in more "traditional" chanty style, at slower, windlass tempo.
