(FORTUNE Magazine) – Do corporate rock & roll bands reflect the inner soul of a company? I would argue yes. Fortunately I had the perfect proving ground to confirm this hypothesis: FORTUNE's second annual Battle of the Corporate Bands at the Rock and Roll Hall of Fame in Cleveland. And I wasn't just attending this boondoggle. I, Dr. Street Life, was the MC! I was a little skeptical at first, but it turns out the bands rocked! Some of the highlights:

The Marsh Blues Brokers sprang from Marsh & McLennan's Atlanta office. Company does insurance brokering, etc. Marsh's stock has been a proven winner over the long run. Lead singer Jonda Madison sang one heckuva version of "I'm The Only One," by Melissa Etheridge. Marsh also brought along a wild cheering section. As I said, a proven winner.

The Raving Daves from PeopleSoft are named after David Duffield, former CEO and now chairman of this Bay Area HR software company. Though P-soft (not to be confused with P-funk) has had it rough over the past four years, the band has been going strong since 1992. Ten years of experience served the Daves well; they did an especially tight version of "Lady Marmalade" and took first prize! Hey, Ellison, does Oracle have a band? The Flaming Larrys?

Get your motor running. From Milwaukee comes Parts Rock and Accessories Roll, the house band of Harley-Davidson. Like its band, this company looks to be firing on all cylinders. But a Wall Street contingent says Harley's gains are coming from its financing unit, not Hogs. The company says that's hogwash. Maybe the band was trying to reinforce that notion when it played a tune by No Doubt.

Also straight from Milwaukee (that city has soul!) were the Briggs Bluesbusters from engine maker Briggs & Stratton. They did a nice, eclectic set--Led Zep (a metal tune from a metal company), the 'loaf's "Paradise by the Dashboard Light," and one of my fave tunes of the night, "Briggs & Stratton Man," a warped corporate jingle. Briggs has been kind of idling along for the past couple of years; maybe a new jingle would do it some good.

None other than Richard Scrushy, controversial chairman of HealthSouth, fronted his band Proxy (as in let me vote yours). Scroosh, who's never been accused of an inferiority complex, sang lead on an original composition, "Too Good-Lookin'." Hmmm.

Ladies and gentlemen, the greatest rock & roll band in the world: the Rolling Bones! A bunch of guys from different Wall Street firms playing Stones tunes pulled off an edgy set. "Paint It Black" and "Midnight Rambler"--but no "Brown Sugar." Hey, that's what working on the Street is all about: taking risks.

All in all, an amazing night. Do the bands reflect their workplaces? As I just showed you, of course they do. And as Charlie Daniels once said, "God bless America. Again."
