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"
