12a Conductor typically came together with a new driver. Ans was metal.
I can see that a metal is typically a conductor of electricity and that a golf driver can be metal. Came together =met + a =meta but where does the l come from?
22a Artist carrier's taken round the whole of Ireland. Ans was ballerina.
A ballerina is an artist (or should be artiste?) Erin is a word for Ireland but just can't see where balla comes from.
I've spend more time trying to work out the wordplay for these two than it took the solvers to finish the crossword!
Thanks
