"Ay, yi, yi, yi," is a common introductory line of verses of the Inferior Bawdy Celts of Eire, and sung to the Gaelic tune of "Cielito Lindo", with 3 improvised lines like, "I'd rather get laid than get eaten, So sing me a chorus, While I eat your Clitoris," and ending with something like "So waltz me around again Willie". There are some examples sung by the decadent Gaelic nightingale Rusty Warren on 'Songs for Sinners', Jubilee LP 2024. Martyn Green just recited samples (Sassenach style) on Riverside RLP 7001. A clan of the Greater Bawdy Celts, around Limerick, from whom the name comes, could come up with 5 lines all on their own. A small sample of 1739 of these little rhymes was laboriously translated into English, and given by the notorious Celtic schollar Gershon Legman in a small book imaginatively titled 'The Limerick', with a few supplementary ones (2750) in 'The New Limerick'. Rumour has it that some misguided soul, doubtlessly to discredit the Celts, made up a non-bawdy Limerick, but so far it's eluded my searches.
Further meticulous research, aided by discovery of The Greater Book of the Bawdy Celts under a French title, and its translation into English has given rise to a further report on the poetic, musical, and historio-erotic remains of the early Celts. This is combined with the earlier report, available via Old Blue.
