New fag stag Barack Obama better watch out, because Hillary Clinton's called in the Queen of all gays, Elton John!

The legendary pianist will perform a Madison Square Garden Radio City Music Hall concert for Mrs. Clinton on April 9, the first time he's played at the venue since 2000. John's so psyched about Clinton's candidacy, he even wrote a personal letter to supporters:

There is nothing I like better than throwing a party for a good friend. Will you come out to support my friend Hillary Clinton at a special, one-night-only solo concert in New York? I promise this will be one night that you won’t want to miss.

That's some real heart. And it's got a price tag: $250-2,300 a ticket or $10,000 to get all VIP with John and the Clintons. Start counting those pennies!
