AH, the songs are from the Republican Army, the IRA, who used to think (most likely still do) that English/UK Military Personnel made quite good targets. Look at the Poppy based Avatars that are being displayed at the moment, think about the time of year, and what it signifies, (if I remember rightly you don't agree with it, that's up to you)
I never served there myself but I lost friends there, and was in Deal when it was bombed in '89, and object to Jordy publicising the IRA, especially at this time.
