Mason Williams was more a cult figure than a star of the sixties, but he did contribute at least two good things: the guitar piece called Classical Gas and the following poem.
Moose Goosers
Look at them moose goosers, ain't they obtuse?
Up in them boondocks goosing them moose.
Goosing them huge moose, goosing them tiny
Goosing them meadow moose in they hiney.
How to be a moose gooser - it'll turn you puce,
Just get your gooser loose and rouse a drowsing moose.
