Yes - I wasn't comparing the music of Nic and Bert - just the recording quality. I've got most of the Leader/Trailer recordings, and there's certainly a family resemblance in the collected LPs.

I don't mind Bert - used to be quite a fan 40 years ago, not very much now - but I got seriously pissed off by the pretentious sleeve notes on the first album, written by one Keith de Groot (whoever he was).
