NILES Ð When musicians record, they're often seeking a "happy accident" to capture an inspired moment, which, in the Van Dyke Revue's case, turned out better than they imagined.For singer, guitarist and harmonica player David Van Dyke, that moment came when drummer Kurt Allsop posed a crucial question after a gig one night. "He sat in with us, and said, ÔYou guys wanna record?'" Van Dyke said. "He thought our stuff was pretty good, and we liked it so much, we kept him as the drummer."To celebrate its self-titled CD, "The Van Dyke Revue," the band will host a launch party that starts at 7 p.m. Saturday at The Riverfront Cafe, 219 N. Front St., Niles. For further details, go online to http://www.vandykereveue.org or call (574) 220-8263.The band promises something for everyone, starting with an acoustic set from 7 to 8 p.m., Van Dyke said. "Then, from 8 to midnight, we're going to do our rock 'n' roll set that we play every weekend, and we're going to premiere some of our original material."The Riverfront seemed like the logical choice, "because we played there every weekend, our following is Niles Ð where most of us are from Ð and it's a real central location," Van Dyke said. "People know that we're there."The band's core consists of David and his father, John, who sings and plays guitar, piano and violin, and also designed the CD cover and insert art. John began teaching his son the guitar in 1986, which led to them performing acoustic duets in church, according to the band's biography. The pair formed the Van Dyke Revue in 1998.The family's roots are in education. John teaches art at Sam Adams Elementary School in Cassopolis, and David teaches math and science at the Clay Intermediate Center in South Bend, Ind. Singer-bassist Kevin Healy and Allsop, who also produced the CD, complete the lineup.Van Dyke describes the Revue as a true variety band that's capable of playing about 300 cover songs. "We have songs from the antebellum South and songs that are relatively recent, from the Traveling Wilburys and Tom Petty. We do some by Nat King Cole, Elvis, the Beatles. If we don't play a song you like within the first set, we'll refund your money," he said.Judging by the response to the Revue's online presence, that may not an issue Ð including the 28,000 hits generated for www.vandykerevue.org and 15,000 "friends" added to its other main page, www.myspace/vandykerevue.com.The band did its CD at Bo Knows Records Studio, the South Bend recording setup and label run by Allsop Ð himself an accomplished instrumentalist presence on bass, guitar, drums, mandolin, piano, violin and viola, Van Dyke said.Two singles released online have already elicited a strong response, including the instrumental "Lakehouse Reprise," which logged a No. 1 position last May on Gain Central Radio, the biography said.Among the CD's notable tracks are "Ode to JD," a tribute to the sunnily positive singer-songwriter John Denver, who died in a plane crash in 1997. "I used to live in Oregon, and if you'll recall, he died right around the same time Princess Diana died," Van Dyke said. "It really superseded the coverage that I felt he should have gotten. My wife really liked him, and was feeling sad about it Ð so I said, ÔHere, I'll write this song.'""Sellout," on the other hand, drew its inspiration from Van Dyke's experiences playing in a different band, he said. "We did all originals, only played what we wanted to play," Van Dyke said. "Then I realized that you have to play ÔBrown-Eyed Girl' every Saturday night if you're going to get paid to play. The people I used to play (with) told me I was a sellout for doing it Ð it's kind of my answer to them."Plans call for recording a new acoustic-based CD this winter. Asked if the band holds out any greater ambitions, Van Dyke responded, "I think how well the (current) CD does will let us know that. My dad and I are teachers, and teachers have summers off, so we have more time to perform. I think we'd like to organize a tour next summer, a whole Midwest tour."
