A lot of my favourite parts don't have words - they're the "oooo-oooo" moments (and other vocal sounds!).

WDIDWMH: When Don sings "I'll love you til death do us part" (Glenn's wooo-ooo is stunning)

The breath sucking in OOTN, as well as the line "You've got desires, well I've got a few of my own!!"

LROOE - I love the sense of vertigo when Don goes from singing about the blackness of an endless night, galaxies unfolding, and new worlds being born - then "I'd give anything to be there in your arms tonight" feels so immediate and almost as though I'm physically dropping from the stars into his arms (wishful thinking!).

Already Gone - the "we never even know we have the key" line

Doolin Dalton Desperado Reprise - the harmonies on the Desperado part.
