How in the world could Elton John be strapped for cash? Aside from his continuing stream of royalties from his prior hits, he's one of the most prolific touring artists in the world. Plus, he just came off that long engagement in Vegas (the Red Piano at Caesar's) for which I understand he made well over $30 million. It was the second most successful show in the history of Vegas.
If he actually played this wedding, although I do understand he does play private events with some frequency, I'll be shocked.
He's also regarded as one of entertainment's biggest spenders.

Elton has had MAJOR money problems in the past. He spends it as fast (or faster) than he spends it. Here... Google is your friend...
