Our selection has words and music by Brent Hardesty. Ever heard of him? Me neither. It took a fair amount of digging to find out anything about him; but he's quite interesting. He lives in the Baltimore area and has done all sorts of jobs in music: elementary and middle-school music teacher, audio producer, lounge pianist, wedding pianist, and jingle writer for local advertisements. All this and songwriting too, including "The Night the Lights Went Out" about the closing of Memorial Stadium, CD's of which were sold at Baltimore McDonalds restaurants in 1991. You have to admire his versatility. His text uses elements of the original story to tie into a more generalized message of hope and faith. "Eight Candles" was arranged by Ed Lojeski, another versatile figure in the musical world, albeit someone a little better known. I can't do better than quote from his page on singers.com: "Ed Lojeski is a prolific writer of pop choral arrangements that are designed to bring maturity of sound to the young chorus and an edge of excellence to advanced groups." Maybe the men of the Chorale can perform his Beach Boys arrangements one of these days.
