i love/hate making lists like these because i always end up wanting to change my answer, but it's still fun to do.. here goes..
1.) John Lennon
2.) Jim Morrison
3.) Eric Clapton
4.) Jesse Lacey (my favorite song writer..)
The 4 above mentioned would make ridiculously amazing music and provide the soundtrack for the night..
5.) Hunter S. Thompson
6.) David Lynch - i'd pester him all night to tell me what Mulholland Drive is about :)
7.) Alfred Hitchcock (not to steal Miles answer or anything.. but i'd REALLY want him to be there..
8.) Chuck Palahniuk
9.) and someone from political history.. like Karl Marx or Thomas Paine to make some sense of the world today..
10.) Audrey Hepburn - sitting right next to myself, acting as my date for the night :D..
This would be the best dinner party ever.. great music.. great conversation, and Audrey Hepburn "helping me in the kitchen" to prepare dessert..
