"Danny Boy" is often seen as an Irish standard, and some consider it symbolic of the Irish diaspora that began around 1850. But Foley's Irish-born owner, Shaun Clancy, calls it depressing -- and he notes that it was written by an Englishman who never set foot in Ireland.
Clancy declared "Danny Boy" off-limits last month, including on St. Patrick's Day.
The lyrics were published in 1913. The song has since been recorded by such star singers as Bing Crosby, Elvis Presley and Johnny Cash.
