Lyrics:

Three is a magic number
ya it is, it's a magic number
Somewhere in that ancient mystic trinity
You'll get three
As a magic number
The past, the present, the future,
Faith, and hope, and charity,
the heart, the brain, the body,
will give you three,
it's a magic number

It takes three legs to make a tripod or to make a table stand,
and it takes three wheels to make a vehicle called a tricycle
And every triangle has three corners,
every triangle has three sides,
no more, no less,
you don't have to guess
that it's three
can't you see?
it's a magic number

A man and a woman had a little baby
yeah they did
and there were three in the family
and that's a magic number

3, 6, 9,
12, 15, 18,
21, 24, 27,
30

Now multiply backwards from 3x10
3x10 is 30
3x9 is 27
3x8 is 24
3x7 is 21
3x6 is 18
3x5 is 15
3x4 is 12
and 3x3 is 9
and 3x2 is 6
and 3x1 is 3 of course
(Now dig the pattern once more!)

3, 6, 9,
12, 15, 18
Oh yeah

3x10 is 30
3x9 is 27
3x8 is 24
3x7 is 21
3x6 is 18
3x5 is 15
3x4 is 12
and 3x3 is 9
and 3x2 is 6
and 3x1
What is it?
3

A man and a woman had a little baby
there were three in the family
and that's a magic number
