Elton John made Touching Tribute to the Late Whitney Houston

Sir Elton John canceled two concerts this weekend after he came down with food poisoning.

The 'Rocket Man' singer had been due to play at Caesar's Palace in Las Vegas on Friday (02-17-12) and Saturday (02-18-12) as part of his Million Dollar Piano residence, but pulled out after something he ate left him too ill to sing.

A spokesperson for the star told website TMZ he is feeling "much better now" and will be ready for his next concert later this week, in Guadalajara, Mexico.

Elton was performing in Las Vegas the Saturday before (02-11-12) when he heard about the death of Whitney Houston - who was found passed away in a hotel in Los Angeles ahead of the Grammy Awards - and dedicated his track 'Don't Let the Sun Go Down on Me' to her.

Addressing the crowd that night he said: "This is a sad day today, most of you must know by now the news of Whitney Houston passing away.

"About six years ago I was here in Vegas with some friends and we spent the whole afternoon on YouTube looking at Whitney's work from a long time ago, and you forget - with all the troubles she went through - how brilliant, she was.

"So, my dearest, gorgeous, lovely angel, we want to do this song for you. Thank you for giving us your talent and one of the most beautiful voices I've ever heard in my life."
