Three is the magic number
  yes it is its a magic number
  Somewhere in this ancient mystic trinity
  you got 3 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
  
  Takes three legs to make a tripod and to make a table stand
  Takes three wheels to make a vehicle called a tricycle
  Every triangle has three corners, every triangle has three sides
  No more no less you don't have to guess
  when its three you can see its 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
  whaoo
  
  3 6 9 12 15 18 21 24 27 30
  3 6 9
  12 15 18
  21 24 27
  30
  
  now the multiples of three come up three times in each set of ten
  in the first ten you get 3 6 9
  and in the teens ten you get 12 15 & 18
  and in the twenties you get a 21 24 27
  and they go down even on 30
  
  Now multiply backwards from 3 time 10
  3 times 10 is 30
  3 times 9 is 27
  3 times 8 is 24
  3 times 7 is 21
  3 times 6 is 18
  3 times 5 is 15
  3 times 4 is 12
  and
  3 times 3 is 9
  3 times 2 is 6
  and
  3 times 1 is 3 of course
  
  now repeat the whole pack again
  (3) 3 6 9
  (12)12 15 18
  (21) 21 24 27
  (30) 30
  
  
  Now multiply backwards from 3 time 10
  3 times 10 is 30
  3 times 9 is 27
  3 times 8 is 24
  3 times 7 is 21
  3 times 6 is 18
  3 times 5 is 15
  3 times 4 is 12
  and
  3 times 3 is 9
  3 times 2 is 6
  and
  3 times 1 is the magic number
  
  A man and a woman had a little baby, yes they did,
  They had three in the family and thats a magic number
