It's "charity dance" with me. It's easy to blur into "cherry" as his voice drops after the start of the word, or if you aren't using good headphones, but you should be able to make out the "i" sound separate from the "ty." As for the sense, it's from the poem 'I am of Ireland' by Yeats, from his collection 'The Winding Stair and Other Poems' (not spiral
) - one of the most plundered collections of poetry by the pirates of rock, as you'll find bits lifted by Led Zeppelin, Kate Bush, and Van Morrison in there among others.
To quote a bit:
"'I am of Ireland
And the Holy Land of Ireland
And time runs on,' cried she.
'Come out of charity,
Come dance with me in Ireland.'" etc. - it's basically the chorus to the poem. And, of course, Yeats lifted it himself apparently from an Olde Englishe pome:
"Icham of Irlaunde
ant of the holy londe
gode sire pray ich thee
for of saynte charite
come ant daunce wyt me
Anyway, I'd say that's the easier line, and its sense turns on the themes that run through UF & JT. The more difficult line is "an eye like a firework, Erin, explode -- a Roman candle and lightning lights up the sky" -- a line with heaps of sense (provided it's correct
), and perhaps the most important line on the album.
