Elvis Presley's daughter Lisa Marie Presley was only nine when her legendary father died suddenly. She wrote in her memoir that she could never forget her grandfather's 'wailing'

When Elvis Presley's only child, Lisa Marie, died aged 54 last year she left behind an intimate request: for daughter Riley Keough to finish off her memoir based on recorded tapes and their time together.

The late singer wrote that she "planned and plotted and schemed" to make sure she was ovulating when she joined her then-boyfriend on a cruise ship in the '80s.
