My first guess would be "Duet", also. Clark was a widower with a young son, and always trying to stay one step ahead of Child Services because of his unusual lifestyle (as a musician) and because his child had been traumatized by his mother's death (though Clark's marriage to Lana wasn't a happy one) and no longer spoke. Lois was an entertainment lawyer or something like that, and they met in that capacity.
