3 Is The Magic Number
Original Artists: George R. Newall

Three is a magic number
Yes it is
It's a magic number
Somewhere in the ancient, mystic trinity
You get three as a magic number

The past and the present and the future
Faith and Hope and Charity
The heart and the brain and the body
Give you three as a magic number

It takes three legs to make a tri-pod
Or to make a table stand
It takes three wheels to make a ve-hicle
Called a tricycle

Every triangle has three corners
Every triangle has three sides
No more, no less
You don't have to guess
When it's three you can see
It's a magic number

A man and a woman had a little baby
Yes, they did
They had three in the family
And that's a magic number

Three, six, nine
Twelve, fifteen, eighteen
Twenty one, twenty four, twenty seven
Thirty

Multiply backwards from three times ten: 
Three times ten is thirty
Three times nine is twenty seven
Three times eight is twenty four
Three times seven is twenty one
Three times six is eighteen
Three times five is fifteen
Three times four is twelve
And three times three is nine
And three times two is six
And three times one is three, of course

Now take the pattern once more:
Three!... three, six, nine
Twelve!... twelve, fifteen, eighteen
Twenty-one!... twenty one, twenty four, twenty seven... thirty

Now multiply from 10 backwards:
Three times ten is thirty
Three times nine is twenty seven
Three times eight is twenty four
Three times seven is twenty one
Three times six is eighteen
Three times five is fifteen
Three times four is twelve
And three times three is nine
And three times two is six
And three times one...
What is it?
Three!
Yeah, that's a magic number

A man and a woman had a little baby
Yes, they did
They had three in the family
That's a magic number
