LOS ANGELES – Legendary Australian hard rock group AC/DC opened the 57th Grammys with a bang on Sunday night, performing their new single "Rock or Bust" and the iconic "Highway to Hell."
But it seems all those decades of rocking out means lyrics -- even to your own song -- may require a little help remembering.
The Hollywood Reporter's Matthew Belloni, tweeted out an image of the large teleprompter positioned at the back of the Staples Center, showing the lyrics being flashed as they were sung by lead vocalist Brian Johnson.
AC/DC were without founding rhythm guitarist Malcolm, who is enduring numerous health issues and has been replaced by his nephew Stevie Young, and teleprompter or not, their blistering two-song set was well-received by both the Grammy crowd and those on social media.
"AC/DC rules," wrote Rose McGowan. "I want to be Angus next Halloween."
Scores of other called it "the best of the Grammys," "amazing" and a "triumphant" return for the hard rockers.
The performance also marked Chris Slade's first live showdown with the band since 1994, as he took the reigns from original drummer Phil Rudd, who is waiting on a court appearance in his homeland of New Zealand pertaining to a string of recent legal woes. Rudd was with AC/DC from 1975 through to 1983, and was then replaced by Slade. Then in 1989, Rudd came back in and succeeded Slade.
It remains unclear as to who will drum for the band as they continue to tour in promotion of their latest studio album "Rock or Bust," which dropped in November. AC/DC is scheduled to perform at this year's mega Coachella Festival in April, and will continue on a world tour this year.
