Do you know this tune? Do, do, so, so, la, la, so, Z | fa, fa, mi, mi, re, re, do__|| ?

Nope.  I know

Do, a deer, a female deer 
Ri, a drop of golden sun 
Mi, a name I call myself 
Fa, a long, long way to run 
So, a needle pulling thread 
La, a note to follow So 
Ti, a drink with jam and bread 
That will bring us back to Do (oh-oh-oh) 

That is the system, but not the tune. If you know what each sound is, you will know the tune. Thanks!
