Pop superstar Michael Jackson tried to make a musical comeback on Wednesday but his attempt appeared to be a great disappointment for thousands of his fans.
He was singing the chorus line of his charity single We Are The World before the sound cut out as he struggled for the high notes.
"There have been so many people who have loved me and stood by me. I love all the fans from the bottom of my heart," Jackson said from the stage.
He then threw his black jacket into the crowd and spent time shaking hands with people in the front row before leaving the stage, CBC.ca reports.
The 48-year-old, performing live for the first time since he was acquitted of child molestation charges in June 2005, had been expected to sing his seminal hit Thriller.
But to the huge disappointment of screaming fans, that was performed instead by young U.S. star Chris Brown.
Jackson's failure to demonstrate his voice and confidence were back was likely to raise further doubts about his ability to resurrect a career that has been on hold for years.
Earlier in the evening, Jackson was given an award honoring musical artists who sell more than 100 million records, chron.com says
