There were times during the go-go '80s — and we have the deliciously dated videotape to prove it — that Gary Shane would pull double duty, playing in the opening and headlining acts — exchanging the goofy cowboy hat he wore with Alan Laddd and the Abashed, his country-tinged side project, for the de rigueur skinny tie for his power-pop band The Detour. Well, time flies. More than two decades have passed, but there he goes again. The Ipswich rocker has not slowed down at all. Or learned his lesson. In fact, he's going to redouble his efforts, literally. Shane will be front for four (count em, four) bands — The Detour, The Silvertones, Alan Laddd and the Abashed and, where it all got started more than a quarter-century ago, the Shane Champagne Band — during the Japan Disaster Relief Concert, a four-hour shebang set to ... Nah, scratch that. Make it five. He’ll also play in Imojah and the Skylight Band, the reggae act fronted by ex-Cultural Roots singer Wade Dyce. We hear there’ll also be a few other acts on the bill. We’ve heard some names, but aren’t saying nothing until it’s nailed down. Except for Asa Brebner and Friends, because he’s on the poster. Shane will probably be playing with him, too, but we’re hoping that Brebner will bring along some other friends, like, um, maybe the girl singer from that band he was in... what was the name? Oh, yeah. Robin Lane and the Chartbusters. Here’s to hoping. The gig had originally been scheduled for the Rowley VFW, the site of Shane’s last benefit concert — for the 2004 tsunami that battered Indonesia. At that show he opened for a sock puppet performance, a la Spinal Tap. Ah, good times, good times. The show runs from 4 to 7 p.m. April 17 at Ipswich Town Hall, 25 Green St. Tickets are $10 and can be purchased at the door. For more information, check out Shane's web.
