A teeny cryptic crossword

I promise, I had the idea for a 5×5 cryptic before Graylocke!

Clues:
1A Record side conversation. (5)
4A Demand previous show. (5)
5A Butcher lead-free paint. (5)

1D Revolutionary invention is "essential to law", he elaborated. (5)
2D Country’s capitals?? Of interest, take a look, yeah. (5)
3D Weekly repetition (Rent! Rent!) provides a key, perhaps. (5)

This is my first "full" cryptic crossword (and my first cryptic puzzle that I didn’t have someone else check first!), and I’d appreciate feedback on my cluing.
