Using The Bootstrap Paradox

This weeks Doctor Who had a strange introduction with the Doctor struggling with the Bootstrap Paradox.
He said that he went back to see Beethoven but he wasn't much of a music writer so he noted down his 5th Symphony which he then played and became famous with.  
The headache comes because the Doctor could only write it down because he had heard Beethoven play it but Beethoven had only played it because the Doctor had written it down for him but the Doctor had only written it down because he had heard Beethoven play it...and so on.
I have always planned to go back to the late 80s and hand the famous Hanson song 'Sweet Child Of Mine' to a semi-famous band like Guns 'N' Roses who would do a much better job of it, the song is crying out for loud, screeching guitar solo and i am sure someone like Slash could do a much better job on his Les Paul Guitar of that pathetic mid-song recorder solo by the Hanson's.
Anyway, first chance i get i will do it and hopefully make Guns 'N' Roses famous (and Hanson don't rise to the stratospheric heights where they currently sit which would be a bonus), but i hope i have more luck then i did with handing the most famous Heavy Metal song of all time, Copacabana, to Led Zeppelin.
They didn't fancy it and as a punishment i gave it to some young guy called Barry Manilow who i feel will do it justice, hard rock style so keep your ears open.
That's what is so good about the Bootstrap Paradox, you can take something back in time and give it to someone else so for example, for giggles, write down the theory of relativity and give it to the janitor or whisper the idea of a singing competition the public vote for the winner to the record companies tea boy.
