353H: Young Singing Boy Dies As Old Man Under Tree

I am trying to find a book I received as a child in the early 1980s.
The book had a white cover and was the story of a young boy who grew up with the talent of singing. It chronicles his life and then ends with him dying as an old man under a tree a believe…a place that is often referred to in the book I think.
The illustrations are all stick figures.
I believe the story was inspired by Elvis and their may have been a dedication to him or something in the book.
I would really love to find a copy and remember this book since I can’t find my copy.

345B: Musical Love Story from Harlequin Era

I'm looking for a book which may be Harlequin from late 1970s or early 1980s, about a young widow of a rock and roll band member who may have committed suicide. She falls for his band mate, who has long been in love with her, and it turns out, she has a hidden singing talent. I believe the setting is at a beach house, in Florida perhaps.
