Madonna: The past is past, and cannot be revisited. Except for a price.

We're sure she was almost half joking when Madonna ruled out playing her decent songs unless there was a big cheque in the offing:

"I'm not sure I can sing Holiday or Like A Virgin ever again.

"I just can't - unless somebody paid me like $30 million or something. (Like if) some Russian guy wants me to come to the wedding he's going to have to a 17-year-old."

Half joking. But she's set up a PayPal account, just in case.
