Following an introduction by Haiti native Wyclef Jean, R&B singer Mary J. Blige collaborated with opera star Andrea Bocelli live on stage Sunday night (Jan 31) at the 2010 Grammy Awards in Los Angeles and the duo sang Simon & Garfunek’s “Bridge Over Troubled Water,” which was dedicated to the people of Hait.

Another duet of the night came from country music sensation Taylor Swift and rock legend (and former Fleetwood Mac member) Stevie Nicks, who performed an off-key version (courtesy of Swift) of Fleetwood Mac’s “Rhiannon” before moving on to Taylor’s hit single “You Belong to Me.”

And following his performance of “Pretty Wings,” R&B crooner Maxwell brought out R&B legend Roberta Flack for a duet of Flack’s “Where is the Love.”
