Yeah, I'm sure you think you know how to do it, but trust me, unless you sat next to my friend David while watching the greatest movie of all time (his words), YOU DON'T.
I was recently on vacation with a handful of friends and on the final night of the trip, we popped in the DVD version of The Sound of Music that has the singalong version on it (yes, two people went to bed immediately). All that means is they put the words to all the songs on the screen during the musical numbers like subtitles. And by the way, all the songs are faster than you think. Like when you sing them while vacuuming -like you do, I'm sure - you sing them at a certain speed. But you aren't singing them fast enough, trust me, no matter how fast you are singing them. The big mystery for me is why is the movie eight hours long if the songs go so fast? And why do they show it at Christmas? There's not a Christmas scene in the whole movie. I've never gotten that.
But ANYWAY lemme tell you...David didn't need the subtitles. And not just for the songs. He recited almost every line of dialogue before the actors did. In a way, I wished we had just watched him do it; it would have been an hour shorter. Seriously, it was like watching Rainman perform the Collected Works of Shakespeare. I won't bore you with a song-by-song replay, but at one point he got up and moved to the other side of the room, telling us we were making him sing off key. As if. You should try it sometime, the singing along. That Do-Re-Mi song is like running a goddamned marathon.
