Thank you very much Gabriel, I see them both now.
It's odd that 9d uses a 3 letter abbreviation that is means both a word in the clue and the answer! - I don't think I've ever seen that before.
I just guessed at which is left and right but it looks like I was lucky.
I say 'looks like" because my 'earlier situation' doesn't seem to have much to do with the song - at least it's not part of the lyrics but, when I Googled it, it was followed by a word that is in the song.
