Uuhhmm--as a song to celebrate freedom, maybe. But how does a song about Irish sailors & priests relate to the day the slaves in Texas (& other Southern states) got official notice that they were free?? That's what the date signifies--June 19,1865--the day the official announcement was made by an officer in the Union Army as they re-established the fact that Texas was again(still?) a state in The Union....Tw
