Cover art for Hey Day lyrics by Mic Christopher

this song is indeed from the guinness ad but it should not be remembered purely for thsi reason. mic christopher was a hugely talented man and a legend in his own right. this song is about how when everyone is old they speak of their "heyday" and mic thought it appropriate to right a song while he was and while we all are in our heyday! its a beautiful song written by a beautiful person who died too young
