First up is Bare Trees by Fleetwood Mac. Released in 1972 by the group's original lineup and written by Danny Kirwan who was fired by the band later that year. This album and song seems to get lost with the monster mid-seventies addition of Stevie Nicks and Lindsey Buckingham.

Next is Hazy Shade of Winter by Simon and Garfunkel, first released in 1966 as a single and then included in the 1968 Bookends album. I always loved this song because it showed the boys could rock 'n roll with the best of them. My guess is that this song with its quintessential beat influenced other groups in the mid-60's.
And lastly, California Dreamin' by the Mama's and Papa's, released in 1966 on the If Your Can Believe Your Eyes and Ears album. You'll be singing this song in your head again, like you have done so many times before, on such a winters' day.
