Memorial 4 was for a friend from the YMCA, Peter McCabe. (His brother Charles was a columnist for the San Francisco Chronicle for many years.) It is in the form of a nineteenth century overture. I've not used the "Danny Boy" tune to represent his Irish-American background but because it was a favorite of his and he sang it often in his high tenor voice. His happy-go-lucky personality is mirrored in the rather jaunty music of the beginning.
The origins of the tune, also known as "Londonderry Air" are shrouded in mystery (It's possibly Scottish.) but the words were definitely written by an English lawyer, Frederic Edward Weatherly (1848-1929) and published in 1913.
