Singer Randy Jackson was forced to skip a planned visit to his brother Michael's grave on the fourth anniversary of his death on Tuesday (25Jun13) after he was struck down with a throat infection. Fans of the King of Pop gathered at Forest Lawn cemetery in Glendale, California to pay their respects to the late superstar and Jackson reveals he had hoped to join them at the grave site - but he's suffering from strep throat. In a series of posts on Twitter.com, he writes, "Thinking about my brother on this day. Thank U everyone 4 your love and support and 4 the beautiful displaye (sic) of flowers at ForestLawn. "I know he would love it. I wish I could be there with you but unfortunately I've been sick with strep throat. Thank you again for your endless love and support". A group of the Thriller hitmaker's devotees arranged to have 13,447 red roses delivered to his grave to mark the anniversary. Michael Jackson died from a prescription drug overdose on 25 June, 2009, and his brothers Jackie, Marlon, Tito and Jermaine have issued a touching statement to TMZ.com expressing their grief on the anniversary of their sibling's passing. The note reads, "Four years ago today we lost one of the greatest musicians, entertainers, and icons the world has ever known. But to us, Michael was first and foremost our brother. We carry his spirit with us always, and we love and miss him every day."
