Mad Professor Blyth is working on his pet invention 
to dematerialise himself into the fourth dimension 
He's got his mind set on illusion 
to find the secrets of diffusion 
Conclusion: he disappeared 

Tried it on his cat one grey night when it was foggy 
Never got it back Oh what happened to his Moggy 
He's got his mind set on illusion 
to find the secrets of diffusion 
Conclusion: he's disappeared 

All the kids around about his neighbourhood 
used to laugh at him and call him names 
Silly old bat freaky four-eyes 

sort of things they used to shout 
He can't hear them now 

He's disappeared 

Colleagues at the lab 
they all thought that he was crazy 
Don't know where he's at 
His formulas to them are hazy 

He had his mind set on illusion 
He found the secrets of diffusion 
Conclusion: he's disappeared
