I saw this one a few years back... a very flighty, irresponsible woman finds happiness as a background singe for a fat, dumpy Elvis impersonator. He has a heart attack and dies so she wanders back to a sort of campground and runs into a woman, evidently a mother-in-law form a short lived marriage years before. The woman says 'what are you doing here?' in an angry voice. Turns out the singer had a daughter years before and abandoned her to grandparents. The rest of the movie is the singer re-establishing a life with her estranged daughter.
Sounds like HIGH TIDE (1987).
