Hooked up with Al after the fight to sing 'Any Old Iron' (5,5)
I believe the answer is:
scrap metal
'sing any old iron' is the definition.
I can't judge whether this definition defines the answer.
'hooked up with al after the fight' is the wordplay.
'hooked up with' becomes 'met' (I've seen this in another clue).
'after' means one lot of letters go next to another.
'the fight' becomes 'scrap' (a scrap is a minor fight).
'met'+'al'='metal'
'metal' put after 'scrap' is 'SCRAP-METAL'.
'to' is the link.
Can you help me to learn more?
(Other definitions for scrap metal that I've seen before include "it's going to be melted down" , "Old estate could be sold as this" , "reclaimed material" , "Get rid of gold, for instance" , "it's unwanted by industry?" .)
