Josh Groban, and Andrea Bocelli
"Expect the unexpected tonight," said Josh Groban, who teamed up with tenor Andrea Bocelli to perform the song "The Prayer" for the first time ever. Groban, whose appearance also marked his debut at the annual pre-Grammy bash, made sure to dress appropriately for the affair. "I got a tuxedo from Dolce and Gabbana," the singer said of his ensemble. "They always take really good care of me."
