3. Peg O’ My Heart
The song was a hit for the first time in the 1913 musical Ziegfeld Follies and composed by Fred Fisher and Alfred Bryan. It was also used as the theme for the BBC miniseries The Singing Detective (1986). In the YouTube excerpt here, a great clip, the singers include the Celtic punk band Dropkick Murphys and The Boss himself (Bruce Springsteen) in Boston.
