That could be good news for Jellyfish. The San Francisco band, which played a sold-out show Friday night at the Coach House, is off to a promising commercial start with "Bellybutton," its catchy pop-fest of a debut album. But if Jellyfish's road to the b ig time should veer into a cul-de-sac, the band will never lack for work as long as nostalgic sons and daughters of the '70s are looking for a good party band. Jellyfish's 80-minute set included a bunch of snappy run-throughs of nuggets from the post-Beatles, pure-pop '70s. Songs like Todd Rundgren's "Couldn't I Just Tell You," Badfinger's "No Matter What," Paul McCartney's "Jet" and Fleetwood Mac's "Go Your Ow n Way" turned up in faithful, boisterous versions that made up in spirit what they might have sometimes lacked in precise execution. It was a reminder that the pure-pop '70s were a fairly happy and fruitful time. Far happier, anyway, than the disco-fied ' 70s, the corporatized '70s, and the metalloid '70s -- all of which seem to have had a lot more influence on subsequent music than the decade's better side. Jellyfish rendered its covers, plus a dozen similarly catchy originals, with a jaunty sense of fun that would be guaranteed to raise a smile from any reunion class. Oversized fake flowers and vines decorated amplifiers and microphone stands. Lead singer Andy Sturmer's stand-up drum kit was wired with Christmas lights, and the band's thrift-shop bouquet wardrobe may as well have been plugged in too. A bubble machine churned out clear capsules of instant childhood through much of the show. On record, the songwriting team of Sturmer and keyboards/guitar player Roger Manning displays an incisive wit and intelligence. That makes Jellyfish a good deal more than a nostalgia band, although nobody could claim bracing originality for these compuls ive Beatles-song bandits. In concert, some of the grace notes and meanings were lost in an often muddy mix. But the band's melodic appeal came through, along with its sense of fun. Jellyfish showed good timing by playing its most serious ballad, "The Man I Used to Be," as an encore number standing apart from more lighthearted fare. Sturmer came across with frayed urgency as he played the protagonist: a dead sailor who laments from beyond the grave as his son prepares to go to fight in the next war. Sturmer led into the tune with a fine, pithy introduction: "Unfortunately, this song means more than when we wrote it. Let's hope it becomes obsolete someday." While his nasal singing was no match for such Jellyfish heroes as McCartney or Badfinger's Peter Hamm, Sturmer was tuneful and enthusiastic enough -- especially with the excellent harmony support he got from the three other members (regular guitarist Jas on Falkner missed the show with a dislocated shoulder, but his replacement, Niko Wenner, stepped in capably). Ensemble harmony singing is an all but dead art among young rock bands who have grown up on too much Led Zeppelin and Aerosmith and groove-obsession, not to mention today's easy-does-it, paint-by-digital-numbers method of mounting vast, unspeakably phony choral backups via electronic enhancement. As if to kick some sand in all their faces, Jellyfish broke into a showy a cappella segment that started with Beach Boys' glee-club "oohs" and ended in Beatles-style breathy "aahs." At this point Jellyfish is no live match for Crowded House or Squeeze, far more experienced bands that carry on the tradition of Beatles-style harmony and catchiness. Both are too advanced to imagine on the bandstand at a high school reunion. But a reuni on with Jellyfish would certainly be worth attending. Standing Hawthorne (formerly the Slugs) is an Orange County band that showed good pop instincts and energy and a sense of political irony during its 40-minute set. But the band needs more practice more than it needed a new name. Singer Paul Schulte's att empts at Bono-style theatricality fell into strident yelping, and the drumming was, to put it charitably, undisciplined (groove-obsession is no good, but groove-neglect can be fatal). First on were the Fishermen, a Los Angeles band that tried to recapture the feel of the Rolling Stones' "No Expectations" or some of the Band's sad balladry -- countrified elegies with a forlorn, exhausted tone. The lead guitar was on target, but samenes s of tone, bland lyrics and humdrum singing blunted the desired effect.
