Sonny & Cher on Letterman, November 13, 1987 (full show, stereo)

One of the top shows in Late Night's 11 1/2-year run, presented in full here and in stereo. First preceded by Dave promoting the appearance the night before and then Bill Wendell's pre-announce. From the repeat of October 8, 1988. (There were two LNs broadcast this night, the first a new show that aired in Carson's slot at 11:30 PM -- the Tonight Show's 26th Anniversary special had aired earlier in prime time -- and then this repeat at 12:30 am.)

Accompanying Cher with her performance of "I Found Someone" and then later with Sonny were John McCurry on second guitar, vocalist Pattie Darcy, and, on synthesizer, Cliff Carter, who was part of the 24th Street Band with Will Lee, Hiram Bullock, and Steve Jordan in the late '70s to early '80s, a band whose second LP in 1980 was produced by Paul Shaffer.

This same ensemble would accompany Cher on SNL a week later on November 21.

That same week later, on November 20, Dave shows a photo that had been taken during the break after Cher's performance.

And, finally, a clip from May 6, 2015, as Cher appears for the final time on Dave's Late Show, here in the same jacket worn 28 years earlier.

With Jeff Martin as Flunky and Gerard Mulligan getting fired again.
