First I'd like to thank all those who answered me and gave me some clues for my study. My thesis is based on three different points. In the first one I draw a parallel between Irish history from 1791 to 1923 and rebel songs. The second one is a study on the Heroes, on the one hand, and on the use of symbols and emblems in these songs. And finally my last point is a study on the tunes, choruses as well as the role of the songs. I was looking for songs of the 70's to conclude my thesis because this period is rich in events and it enabled me to show that the struggle was still going on and that partition did not resolve anything. I would be glad if someone has some remark to make, it could help me as well.
