6. "Your Song" – Ewan McGregor (Elton John cover from Moulin Rouge). "I hope you don't mind that I put down in words how wonderful life is now you're in the world."

She wrote him a song.

After Captain Hammer stopped those muggers threatening her.

He was wonderful. Simply wonderful. There were no better words to describe her hero. The greatest hero ever, of all time!

She became his biggest fan—self-proclaimed.

She traced his every heroic exploit, followed his every step, followed him into the barber to snatch some clippings of his hair, dug through trash to steal his dry-cleaning bill.

She wrote him a song too. A song about how wonderful it was to have Captain Hammer, a real hero around.

She mailed it first class.

She's still waiting for that reply by the time Dr. Horrible catches her eye.
