The Demi Song

The first time I made it up
The demi said to me:
«There's one metal more in group 3.»
The second time I made it up
The demi said to me:
«Chloride isn’t there
And there’s one metal more in group 3.»
The third time I made it up
The demi said to me:
«Iron's there in traces
Chloride isn’t there
And there’s one metal more in group 3.»
The fourth time I made it up
The demi said to me:
«Who said manganese?
Iron’s there in traces
Chloride isn’t there
And there’s one metal more in group 3.»
