Last night (July 21), Sting and Peter Gabriel's Rock Paper Scissors tour stopped by the Key Arena in Seattle. Joining them onstage for a pair of songs was Pearl Jam singer Eddie Vedder, and we have video of both performances.

Vedder first showed up eight songs into the show, for a driving version of the Police's "Driven to Tears," which you can see above. It's not hard to realize why that particular song, which first appeared on 1980's Zenyatta Mondatta, appeals to Vedder, given that its lyrics were inspired by watching news footage of starving children. "Seems that when some innocent die / All we can offer them is a page in a some magazine / Too many cameras and not enough food / 'Cause this is what we've seen."

Two numbers later, Vedder again appeared to sing "Red Rain." As with "Driven to Tears," Vedder sang the second verse of the song, an impressionistic portrayal of nuclear fallout, and traded lines with its creator at the end. You can watch the performance below. The opening track off Gabriel's 1986 blockbuster, So, "Red Rain" was a No. 3 hit at Mainstream Rock radio.

Sting and Peter Gabriel have been on tour since the end of June. Rather than having a co-headlining tour, they have merged bands and sing on the other's songs several times during the night. The tour only has two performances left: Saturday at the Scotiabank Saddledome in Calgary, Alberta, Canada before winding up the next night at Rexall Place in Edmonton, Alberta, Canada.
