With Robert Plant continuing to refuse any and every call to take part in a Led Zeppelin reunion, we thought we'd revisit one of those rare occasions when he and Jimmy Page shared a stage after their 1980 breakup. It took place on Dec. 13, 1983 during the encore of Plant's concert at London's Hammersmith Odeon.

"I've got an old friend here who's unused, as he is, to public speaking," Plant said to an ovation that interrupted him in mid-sentence. "Jimmy Page." They didn't do one of their classics, but instead to an R&B hit that inspired them in their formative years, 'Treat Her Right' by Roy Head. You can listen to it above.

It was the second time Plant and Page performed together after calling it quits. On May 12, 1982, they sat in with Foreigner for a cover of Little Richard's 'Lucille' at the Olympiastadion in Munich. "It was very emotional for Page and Plant because it was the first time they had been together since the death of fellow Led Zeppelin bandmate and drummer John 'The Beast' Bonham two years earlier," Lou Gramm wrote in his autobiography, 'Juke Box Hero.' "It was cool for me to share the stage with Plant because I had always admired his reckless singing style, and some critics had compared my three-octave vocal range and stage presence to Plant's, which I took as a high compliment."

'Treat Her Right' reached No. 2 on both the Hot 100 and R&B charts in 1965. It was kept out of the top spot by the Beatles 'Yesterday.' It continues to be an inspiration to Plant. He also sang the song when he sat in with Los Lobos at the Taste of Chicago in 2010, throwing in a few lyrics of 'D'Yer Mak'er' during the breakdown.
