When The Mike Benign Compulsion took the stage at Turner Hall on Saturday night, the four veteran musicians knew that one of their heroes – REM's Mike Mills – was in the house. The band was opening for The Baseball Project supergroup that – for the tour at least – includes Mills.

By the time the Compulsion kicked off its set, three of the four – singer and guitarist Mike Benign, guitarist Joe Vent and drummer Mike Koch – were aware that Benign had chatted up Mills and convinced him to join them onstage.

The only one that didn't know was bassist Brian Wooldridge, who was celebrating his birthday, and is perhaps the biggest REM fan of the bunch.

Mills (who is on the tour pinch-hitting for his REM band mate Peter Buck) came out to perform "Superman," a song he sang of REM's fourth record, 1986's "Life's Rich Pageant." That tune marked the first time lead singer Michael Stipe didn't handle lead vocals on an REM record.

Vent told me afterward that Wooldridge – who perhaps felt extra pressure since Mills is also a bass player and he had to play Mills' part – was stunned and ashen-faced throughout.

"(It was a) pretty cool and surreal experience for the four of us," Benign said the next morning.

Benign said the band casually worked up the song in rehearsal before Saturday's gig, just in case. It turned out to be a winning gamble.

"We're all R.E.M. fans going back to the earliest days of that band, so we all knew the song," said Benign, "though none of us had ever played it. We ran through it a couple times in rehearsal last Wednesday in case there was an opportunity to do it at the show. Fortunately, Mike was really gracious when we asked."
