I bought a copy of Grattan Flood's History of Irish Music some time ago, chiefly so that I would know where the bulk of the rubbish still bandied about on the subject of tune derivations came from. His work, still quoted uncritically (and usually without attribution) by the credulous is a lasting embarrassment to serious students of Irish music.

He was also responsible for spreading the rumour that the Irish "Union Pipes" were really called "Uilleann Pipes", which is now so widely believed (though there is no historical evidence to support the claim) that people get into fights over it.
