Keith Olsen, in his Q-A here, said they’d “rehearsed Say You Love Me to death.”

Lindsey often speaks of what he gave up to join FM. What he doesn’t talk about is how much joining them provided the structure to become a much better player. Stevie’s singing improved, too: having to harmonize with two singers (instead of just one) probably reined her in.

Christine’s vocals improved, too. But the excellent drums-keys-bass foundation had already been laid years before.

Yes, all of this! It's so clear to me listening to B/N live and album.
The brits made them much better.
