Rise Up Jock was performed on Nowell Sing We Clear by John Roberts and Tony Barrand. It remains on the CD; The Best of Nowell Sing We Clear (Vols 1,2,& 3) I don't know if the written version exists in the US, but the original song was composed in England by Bob Pegg and I believe that it appeard in English Dance and Song. If you are still stuck for the tune I could write it out from my head. Let me know if you need it, and how much detail: harmony, etc. I work with Sibelius. I used to sing the tune with the Morris Team back in the early 80's. The song is essentially musical rendition of the classic central plot of a mummer's play.
