Facebook.com/EltonJohnElton John didn’t see eye to eye with former President George W. Bush when the latter was in office, but he applauds Bush for his efforts in the fight against AIDS.

In an interview with the ABC News/Yahoo! Power Players series, Elton recalls meeting Bush for the first time in 2004, after the then-president signed into law the Emergency Plan for AIDS Relief, helping HIV-infected people in Africa.

Elton -- who once referred to Bush as "the worst thing that ever happened to America" -- says, "I didn't like his policies but I have to say when I met him, I found him charming, I found him well informed and I found him determined to do something about the AIDS situation so I changed my opinion of him.  And his wife was astonishingly kind to us well.  So it was -- I learned a lesson."

Of course, Elton has long been a part of the fight against AIDS, with his Elton John AIDS Foundation.

In the same interview, Elton also applauds President Obama for supporting *** marriage and for signing off on the repeal of the Pentagon's "don't ask, don't tell" policy.
