Todd Rundgren was a customer. 

Todd came in the bookstore and bought a large stack of computer books. No Paris in the twenties for Todd. 

Todd's girlfriend. If you looked Groupie up in the Encyclopedia Brittanica they're'd be a line drawing of her.

Young, tall, and very skinny with a giant poofy fro-like hairdo and hippy like clothes. She looked nice. 

Todd wasn't so nice. I'm not sure if he was having a bad day or if rock stars just don't talk to bookstore clerks. 

I was helping him at the counter and I asked him if he still had Eric Clapton's guitar from Cream.

He made a face and said nastily "Of course I do!"

Huh (later he sold it)

I had to call in his credit card because he was buying so many books.

The operator after hearing the name said "I probably should have said Hello, it's me."

Haha
