Harrigan and Mary’s a Grand Old Name. Continuing on my Irish Journey featuring many of the songs I love to play. Great songs known and sung by most older Americans. “Harrigan” is a song written by George M. Cohan for the short-lived 1908 Broadway musical Fifty Miles from Boston. It was also performed by James Cagney and Joan Leslie in the 1942 film Yankee Doodle Dandy. Mary’s A Grand Old Name also was in the 1908 musical Fifty Miles From Boston. Sing along. I hope you enjoy my little bit of Irish.
