What possibly could be finer than a Friday night out on the town complete with full moon and the sounds of sweet, sweet soul music? Luckily for the crowd at Constitution Hall last night, the question was moot.

The evening's program started with the satiny smooth vocalese of the Shy Lites, best known for their mid-'70s hit "Have You Seen Her." Ray, Goodman and Brown, formerly known as The Moments, followed with a more contemporary approach. Their set was highlighted by the subtly scandalous chart-topper of a few years back, "Inside You."

The headlining act, Chicago's Dells, finished things off in completely over-the-top fashion, decisively stealing the show. With 30 years in show business behind them it was only natural that they sport a high professional sheen, but there was more to it than that.

Backed by a big band--rhythm section, guitar, grand piano and full horn setup--they assailed the audience with hit after hit starting with a boisterous, gospel-like "Get Down With It." They kept the audience at fever pitch with a series of silky ballads and fiery rhythm and blues stompers.

By the time they got to "Stay in My Corner" their audience was totally drained and more than willing to head home.
