More well-known for his quirky, almost novelty type songs like Sunshine Superman and Hurdy Gurdy Man, Donovan whipped this creepy crescendo out with an unlikely gloom not present in most of his work;

What do you think I see ?
Some other cat looking over
His shoulder at me
And he's strange, sure he's strange.

 

 

This is another of the songs in the list that will take your party guests by surprise. They'll bow down before your musical mastery and you can go ahead and take all the credit. It was recently revived in the latest Dark Shadows reboot starring Johnny Depp.
