Former AC/DC drummer Chris Slade is rumored to have rejoined the band in time for their performance at the 57th annual Grammy Awards on February 8.

Slade was scheduled to take part in a meet-and-greet on January 31 at The Optometry Practice of Dr. Alex Corbin Liu in Rowland Heights, California but has postponed the appearance. Liu revealed in a posting on his Facebook page: “There’s actually big news regarding Slade and his career coming in next several days which is why he had to reschedule this event.”

As previously reported, AC/DC drummer Phil Rudd is probably not going to join his bandmates for their performance at the Grammy Awards, which will mark the first time the veteran band has ever performed at an American awards show and on prime time national television. They appeared on “Saturday Night Live” in 2000.

According to International Business Times, Rudd is scheduled to appear in a Tauranga, New Zealand courtroom just two days later, on February 10, for a review of the charges brought against him late last year. Rudd was arrested at his Tauranga home in early November on charges of threatening to kill and possession of marijuana and meth. He is currently out on bail.

The Grammy Awards are scheduled to air live on CBS-TV from the Staples Center in Los Angeles on February 8, a Sunday, at 8:00 p.m. ET.
