Chatting to one of my regular listeners earlier this week, he was most insistent that I check out Loggins & Messina, and particularly their 1974 LP 'Mother Lode'. Their music is very 70s California, and it might just make you feel a bit warmer on a winter's day. I've picked this track off the album called 'Be Free' - which has a bit of everything and the accompanying video takes you through all the seasons. 

Unfamiliar with Kenny Loggins and Jim Messina ?  Bet you're heard this one before: https://www.youtube.com/watch?v=4FDcTyyXQb8
