OK, so it was for one appearance, but what an appearance, with the Acca Dacca frontman and the Foos romping through classic tune Back in Black.
It was recorded for streamed live event VAX Live: The Concert to Reunite the World, with the Foos rampaging through six tracks. The event actually took place earlier this month in Los Angeles, with a live audience mostly made up of essential workers.
Others to appear included Eddie Vedder of Pearl Jam, H.E.R. and Jennifer Lopez.
Right, it’s time to ROCK!
