Jack Johnson fans who've committed to memory every line of every song on each of his three CDs probably won't find any surprises on "A Weekend at the Greek: Jack Johnson and Friends" and "Jack Johnson Live in Japan."

Still, their library of all things Jack would be incomplete without 'em. Both are out today in a two-disc DVD set (Brushfire Films, $24.98).

The films are notable for being the first to feature the Hawai'i-based singer-songwriter live in concert, and offer a taste of just how famous he's become.

"Live at the Greek" was filmed at two near sell-out September shows at Berkeley, Calif.'s Hearst Greek Theatre, supporting Johnson's third CD "In Between Dreams."

"Live In Japan" was shot during a more low-key 2004 tour behind the vocalist's sophomore disc "On and On."

The more upbeat and loose "Greek" disc — with Johnson performing for more than 8,000 screaming, lyric-memorizing fans each night — will instantly ring familiar with anyone who attended his Kokua Festival at the Waikiki Shell in April.

Here, Johnson and his band (bassist Merlo Podlewski, drummer Adam Topol and recently added pianist Zach Gill) crisply breeze through a 90-minute, 19-song set mostly culled from "In Between Dreams" and debut CD "Brushfire Fairytales." A spare stage design — the band, some amps, a couple of candles and nature images on a rear video screen are about it — keeps the music front and center in the large yet intimate amphitheater. A pair of welcome musical guests keep Johnson and crew on their toes.

Beastie Boys keyboard wizard Money Mark does everything but verbally call out versatile pianist Gill to beat down his melodica skills on a crazy funky "Staple It Together." Watching Johnson and longtime musical cohort G. Love deftly match skills on "Rodeo Clowns" and "Mudfootball" in a live setting never gets tiring.

Go ahead and crack up when a few overly enthusiastic female fans down front catch Johnson completely off guard as he begins the first verse of "No Other Way." (Even he has to stop, laugh and chide them.) Grin with a semi-perverse thrill reserved for locals when several thousand Berkeley-ites sing out the "hala ka 'ukulele" verse from "Banana Pancakes" into the California night.

Between-song chats with Johnson and his bandmates and an occasional glimpse of backstage antics make the film feel more like an appealing, funky documentary than a straightforward concert film.

Surf doc directors (and Johnson filmmaking partners) Emmett and Brendan Malloy embue "Greek" with their signature warm, home-movie feel, roaming the stage with handheld cameras and using various film stocks.

By contrast, the 40-minute Emmett Malloy-directed "Live In Japan" intentionally comes off as more subdued musical travelogue than concert film. Dialogue-free, "Japan" instead employs a wall-to-wall soundtrack of Johnson's music to give a stranger-in-a-strange-land overview of the singer's travels.

Skillfully edited concert footage, off-stage jam sessions, and musical montages documenting Johnson's adventures on foot, train, automobile and surfboard make the concept work.

Bundled together in one package (with 30 minutes of extras), these films can't possibly disappoint anyone already in serious like with Johnson or his earnest acoustic surf folk.
