(Yahoo!) - Ed Helms's Andy Bernard character didn't fare too well when he tried to kickstart his singing career on "The Office," but in real life, the "Office"/"Hangover" actor seems to be doing just fine in the music world — if the random participation of buzz band the Lumineers, during Ed's Saturday afternoon appearance at Bonnaroo, is any sort of endorsement.
Ed, who actually moonlights as the banjo and guitar player in his college band the Lonesome Trio, was hosting his "Whiskey Sour Radio Hour" vaudeville-style variety show in the Tennessee festival's Comedy Tent on Saturday, when he invited special guests the Lumineers (who were playing later that night on the much larger Which Stage) out for a surprise "Ho Hey" finale with his band. Good times, of course, ensued.
