Name Some...

[Johnny Stew]

Well, it's a bit intense and somber for some tastes, but I HIGHLY recommend "Man Of The World."
For me, that's the pinnacle of Peter Green's Mac contributions.

From the pre-Buckingham & Nicks years, I also suggest....

Oh Well
Need Your Love So Bad
Albatross
Rattlesnake Shake
I Loved Another Woman
Closing My Eyes
Although The Sun Is Shining
Jewel-Eyed Judy
Station Man
Woman Of A Thousand Years
Future Games
Lay It All Down
Sentimental Lady
Silver Heels
Spare Me A Little Of Your Love
Hypnotized
Why
Prove Your Love
Just Crazy Love

Of course, those songs are just the tip of the iceberg... but should make for a nice starting point.
