IIRC it was "Why Was He Born So Beautiful, and Other Rugby Songs", or one of its successors; there was also an LP, (dis)credited to the Jock Strappe Ensemble. Once they ran out of songs (or town?), they were followed by Rugby Jokes, Son Of Rugby Jokes (cover picture: a small tot sitting at the feet of a field-ready rugby player), and What Rugby Jokes Did Next (cover picture not describable while the wimmin, God bless 'em, are milling about).

Hope this helps.
