You got 8 as I gave separate points for the 3 singers killed in that plane crash.
1. Lonnie Donegan & his skiffle group.
2. Don McLean
3. Buddy Holly, Richie Valens & the Big Bopper
4. Elvis Presley
5. Diana Ross
6. A song that starts quiet & gradually gets louder until it reaches a climax
7. The opposite. A song that starts very loud & gradually gets quieter until it fades.
8. Without music.
9. Bob Marley
10. Where do you go to my lovely? The line is from the verse which goes "Your name is heard in high places.
You know the Aga Khan.
He bought you a race-horse for Xmas.
& you kept it just for fun, for a laugh, a-ha-ha-ha."
Here's the song so you can see for yourself.
