Although the Sixties left us less than a decade ago, people are already waxing nostalgic over them. The best place to do this is where they have the Sixties on wax (along with the Fifties as well). That's at Roadside Oldies, where all the good hits have gone. Rhythm 'n' blues and rock 'n' roll are alive and well at this record shop which buys, trades and sells to collectors or just anyone who wants to relive the past, be it ever so near or far. Floor to ceiling shelves hold everthing you ever wanted to hear on a 45 rpm, from Elvis Presley's original Sun label recording of "That's All Right, Mama" for $300, to $2 re-issues of "Lawdy Miss Clawdy" or "Sixteen Candles." A few spins of "Be My Baby," "Come See About Me," "Blow in In The Wind" and "Eve of Destruction" are guaranteed to vault you back a decade, before everybody traded in their denims for three-piece suits.

Three minutes of yesterday is $2 to $4 for re-issues, double that price for most original cuts. And, if you need something to play all this on, Roadside Oldies will sell you a $2000 vintage Rockola Luxury Lightup jukebox.

Roadside Oldies, 958 Thayer Ave., Silver Spring. Open Monday through Saturday noon to 6 p.m., Thursday till 8 p.m. 587-1858.
