With connections to Monty Python's Flying Circus (he served as a composer and sketch writer for the troupe) and the Beatles (via the brilliant parody group the Rutles), Neil Innes stands as a key figure in British pop-culture history. He also played in the funny-bone-tweaking Bonzo Dog Band, proving that music and humor can fruitfully coexist (ask Death Cab for Cutie). Tonight will reveal if this urban spaceman's clever novelty songs are still mirthwhile. (Triple Door, 216 Union St, 838-4333. 7:30 pm, $15 adv/$18 DOS, all ages.)
