It's The Same Old Shillelagh 
Sure It's the same old shillelagh Me Father brought from Ireland. And Divil a man prouder than He, As He walked with it in his hand. He'd lead the band on Paddy's Day And twirle it round his mitt And divil a bit we'd laught at it OrDad would have a fit 
Sure with the same old shillelagh Me Father could lick a dozen men As fastas they'd get up be gorry, He'd knock'em down again And many's the time He used it on me To make me understand the same old shillelagh Me Father brought from Ireland.
