A clowning Cleo Laine If Cleo Laine didn't leash in her voice firmly, it would run amok and shatter Berklee Performance Center.
It's an enormous, husky, supple voice that finds hidden chambers to bounce off of or whisper through. It can growl. It can also hit a high B-flat squarely.
The great thing is that even with a voice as magnificent as this, she's there to have fun. Laine makes faces, throws in character voices, and struts around. Along with husband John Dankworth and Quintet, last weekend at Berklee, she romped through ''Turkish Delight,'' a bruised ''Send in the Clowns,'' and a staccato ''One,'' from ''A Chorus Line.''
Dankworth, too, has a dry wit, and he and his tight, able quintet play for fun, amiably spoofing the classics. While playing Saint Saens' ''Dying Swan,'' the band slowly expired on stage, tooting to the end.
