"Cum On Feel the Noize" band, 1973 (5)
I believe the answer is:
slade
'cum on feel the noize band 1973' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for slade that I've seen before include "Where in 17 [PORRIDGE] the screws are < put on Noddy and friends" , "small valley" , "Group" .)
