They called off the Radio City Music Hall "debate" that they say was never supposed to be a debate, but now former presidents Bill Clinton and George W. Bush have scheduled a joint appearance next May at the 2010 BIO International Convention — "the Global event for Biotechnology."

The Chicago Tribune says Bush and Clinton "will share a McCormick Place stage May 4, taking questions submitted by BIO President Jim Greenwood after opening remarks by the former Democratic and Republican presidents."

The next day at the conference, former vice president Al Gore (Bush's opponent in the 2000 presidential election), will deliver the convention's keynote address.
