There were only six, not seven: ut, re, mi, fa, sol, la.

[Red Badger]

Well, LA-TI-DA!..................

[dfwgator]

Do - The stuff, that buys me beer
Ray - The guy, who pours me beer

Me - The guy, who drinks the beer
Fa - The distance to my beer

So - I think I’ll have a beer
La - la la la la la beer

Ti - No thanks I’m drinking beer

That will bring us back to (sees empty glass) D’OH!
