medleys by summer include...

"Weird Al" Yankovic

A smorgasbord of Al's lesser-known original songs, approved and retweeted by Al himself. 

Ween

The first of Summer's many amalgamations of Ween's wild and varied ouvre.

Radiohead

A more dark and haunting medley of some of Radiohead's greatest compositions.

K.K. Slider

One of Summer's earliest musical inspirations, this fictional canine from Animal Crossing is a staple in video game music history.
