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.

253F: Collected rock n roll tales

I read a book,12 or so years ago, which I found in my library (I think it had a white cover with black writing and was quite thick), which included articles/chapters about the history of popular culture. there are only two chapters that I can remember- one is about a journalist meeting Dylan in a cafe and Dylan arrives without any bodyguards as he has somehow managed to project a kind of defense around himself and the other chapter had a title along the lines of ‘and the pilgrims visited Kerouac’s grave’ about how ‘kids’ go on a pilgrimage to visit Lowel to see Jack’s grave

I can find no trace of this book anywhere and have been looking for a few years and as stumper has helped me before I place myself in your very capable hands again!
thank you
