The 1x1 is sung, but without interesting rhymes that I had hoped for - that my son has not helped, although he likes poetry and can remember well. So we have the well-known rhymes (6x6 is 36 - lazy ass study hard) even adds: 7x8 is 56 - You notice it to you, then you know the future's 8x8 is 64 - so much candy, that would be splendid So enjoy yourself densities! But stay away from this CD.
