It's time to send summer off with DooWop Denny's annual Silverthorne sock hop, taking place tonight at the Silverthorne Pavilion.Now in its ninth year, the popular event sells out, last year to a nearly 200-strong crowd. Attendees dance the night away to Denny Foley's one-man act, which utilizes computer accompaniment as backup to his guitar and vocals. The people who love DooWop Denny's tunes are "folks who love to dance, and generally those over 50 years old," Foley said, encouraging folks to wear their "dancin' sneakers" in order to make the most of his music, which he promises will "bring out the rock n' roll kid in you" in Silverthorne's elegant ballroom. In sock hop tradition, he'll be focusing on the music of the '50s and '60s for tonight's event, which is the last of his Summit County season before he returns to Florida for his 16th season at the Saltwater Caf in the Sarasota area. This summer, DooWop Denny played weekly shows at the Blue Spruce Inn in Frisco, plus three concerts at the Dillon Amphitheatre. He'll return in June of 2013 for his 14th season. "Summit is an absolutely gorgeous place to be," said Foley. "I think the joy I feel being here all summer long carries through in my vocals and performances." He reports a packed house weekly at the Blue Spruce Inn on Sunday afternoons this summer, not to mention enthusiastic crowds at the Amphitheatre. As to why he has such a big following, Foley said, "I play the music of their youth, with exact vocal inflection, tempo and instrumentation of the original recordings, and with a grin on my face because I'm having as much fun as they are." "A huge thank you to the enthusiastic folks in my audience who have become true friends over the years here in Summit," Denny said. The season was "a whole lotta' fun" and he's looking forward to the finale at the Pavilion and saying goodbye to all his friends. Tonight's dance party is hosted by the town of Silverthorne. Advance ticket purchase is recommended; all major credit cards are accepted. Bring your own munchies and dance the night away.
