Okay- I never thought I'd be posting a lyrics request, since I don't actually sing... but once upon a time I happened on an on-line video of a guy singing a parody of Molly Malone (Cockles and Mussels). It was actually kind of funny but all I can remember is that the chorus had a line that substituted the word "Tacos" in the line that with "cockles and mussels" and the version was set in Mexico, not Dublin.

there is an upcoming wedding between a groom of Irish descent and a bride of Mexican descent and someone really wants to sing this song.

Can anyone help?
