It's dark on observatory hill Come on, let's pretend we're Jack and Jill We'll stroll to the hilltop where college sweethearts go And look at the lights on the campus down below We'll learn what astronomy is for We'll learn what the stars can have in store We'll know in advance the moon may mean romance When it's dark on observatory hill Bridge And I'd like to recite you a poem that I wrote It tells why I think you're wonderful Then from afar we can hear a sweet guitar While voices are harmonizing We don't have to know arithmatic To figure why you and I would click My heart tells me this: your lips were meant to kiss When it's dark on observatory hill
