I like every single song he recorded, but I'd agree that his peak was probably '71-'72. "Hello There Big Boy" might be my least favourite album, but the reasons for its shortcomings are pretty clear. That said, "Spaceman" and "Caroline" are awesome.
I sometimes wonder what the "Second Chapter" songs would have been like if Danny had stayed with Fleetwood Mac. The follow-up to "Bare Trees" might well have included songs like "Cascades" and "Silver Streams", as they were written around the time he left, or soon afterwards.
Having just seen the above post, here's a handy list of the songs he either wrote, co-wrote or sang on while with Fleetwood Mac
If I've forgotten any, I'm sure ChiliD or someone equally switched-on can fill in the gaps.
