This is a new Irish band called Picture This.  We like this song One Drink and the video is good. 

 We voted on a famous old Irish song and agreed this is most popular in pubs and at sports' matches.  Black and Tans refers to English soldiers fighting the Irish in early 19th centuary.  They had many soldiers fighting in WW1 in Europe and so the uniforms were scarce as a result they were left with mismatching uniforms on the island of Ireland.  The Black and Tans were particularly vicious and hated as many were criminals themselves recruited to fight the Irish. 

We have chosen this old Slovak pop song of our parents and grandparents:
