Artist, English youth and composer meeting in German city once (7-8)
I believe the answer is:
munchen-gladbach
'meeting in german city once' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'artist english youth and composer' is the wordplay.
I cannot really see how this works, but
'artist' could be 'munch' (I've seen this before) and 'munch' is located in the answer.
'english' could be 'eng' and 'eng' is found in the answer.
'youth' could be 'lad' (I've seen this before) and 'lad' is found within the answer.
'composer' could be 'bach' (Bach is an example) and 'bach' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
