Lyrics:

Hey, Susan, look who's here!
Well, hello there. Welcome to Sesame Street, gee, we're glad you could drop by.
We certainly are, because everybody's going to be here today. Bob and Mr. Hooper, right, and Oscar and, oh my goodness, and can you guess who else? Gordon, Susan? It's Big Bird. Hi, Big Bird. Hey, Gordon, Susan, there you are. I'm glad I found you. Maybe you can help me.
Oh, we'd be happy to if we can, Big Bird. What's the trouble?
Well, I was just walking down Sesame Street, and I saw a great big long word written on the sidewalk. Mm-hmm.
I Know it's an A word because it begins with the letter "A", but it's such a big word I can't read it. Maybe you can help me. OK, we'll try.
OK. I copied down all the letters on this peace of paper. Mm-hmm. Look at them all. A B, C D, E F G H I J K L M N O P Q R S T U V W X Y Z. That's just about the biggest word I've ever seen! Boy, look at that beautiful absolutely marvelous word!
ABC-DEF-GHI-JKL-MNOP-QRSTUV-WXYZ
It's the most remarkable word I've ever seen
ABC-DEF-GHI-JKL-MNOP-QRSTUV-WXYZ
I wish I knew exactly what I mean
It starts out like an "A" word as anyone can see
But somewhere in the middle it gets awful "QR" to me
ABC-DEF-GHI-JKL-MNOP-QRSTUV-WXYZ
If I ever find out just what this word can mean
I'll be the smartest bird the world has ever seen!

It might be kind of an elephant
Or a funny kind of kazoo
Or strange, exotic turtle
You never see in a zoo
Or maybe a kind of a doggie


Or particular shade of blue
Or maybe a pretty flower
Naah, not with a name like that, Uh uh!

ABC-DEF-GHI-JKL-MNOP-QRSTUV-WXYZ
It's the most remarkable word I've ever seen
ABC-DEF-GHI-JKL-MNOP-QRSTUV-WXYZ
I wish I knew exactly what I mean
It starts out like an "A" word as anyone can see
But somewhere in the middle it gets awful "QR" to me
ABC-DEF-GHI-JKL-MNOP-QRSTUV-WXYZ
If I ever find out just what this word can mean
I'll be the smartest bird the world has ever seen!
ABC-DEF-GHI-JKL-MNOP-QRS-TUV-WXYZ. Big Bird, that's not a word, Big Bird!
It's not?
No, Big Bird, that's the whole alphabet.
It is?
Sure, just read the letters out 1 at a time.
OK. Well, let's see now. A B, C D, E F G H I J K L M N O P Q R S T U V W X Y Z. Why, it is! How about that? It's the alphabet!
