Pop Quiz

I know you all like a challenge so can you help with the last few clues of a local quiz.
All the answers are either singers or groups. There is no clue to the number of letters in each answer.
1 N... sounds like a little fish
2 Keeps grandad ticking over (all I could think of was Jerry and the Pacemakers)
3 Patchy coloured cabin staff (could be something crew)
4 Lightheaded little tyke - maybe 'blonde'
5 Perfect bliss
6 Precious preserve (thought of Jam or Marmalade but that does not include anything to do with precious)

Thanks in advance

Once again friends thats for all your help, no wonder I could not get these answers as I have never heard of them

[THECORBYLOON]

It's Mötley Crüe rather than "Crew" in case you get docked for mistakes.

Now wondering if clue 2 is something to do with a grandfather clock but only coming up with clockwork orange which was a film. Not found there is a group called Pendulum so that must be the answer, and now another quiz is finished. Thanks
