I thought I'd try lipograms, i.e. texts where one letter is omitted. Here's God Save The Queen without the letter 'o': Deity save the kindly Queen we have/ May the refined Queen we have live many years/ Deity save the Queen./ Send her triumphant/ Happy and resplendent/ Under her reign may we spend much time,/ Deity save the Queen. And 'Home on the Range' without the letter 'e': I would gladly stay/among roaming buffalo/and frisking hinds and harts/hardly taking in a discouraging word/noting sky upon sky without day-long cloud.af
