Summer in the city

Wow, things change fast! Lately the weather has gone from dreary and wet early spring/late winter to almost full on summer. Taking the bus to work is becoming an increasingly unpleasant experience (since the city is too cheap to invest in some good AC) and walking in the streets no longer require several insular layers and an umbrella.
And as always in Sweden the sun brings out the good mood in everyone. The first few days of sunshine it seemed like the population of the city doubled or tripled. And it's more or less impossible to feel down or miffed about anything.
All this business with sunshine and happy people milling about has put me in the mood of getting some summer music. Most of what I had was purged from my collection about a year ago when I decided it was time to become more... legal... in that department. I do have a nice little collection of good music. But most of it fits better with fall and winter. Listening to Kent in the blazing sunshine becomes quite a contrast. I'll have to pick up some of the old goodies like Gyllene tider, Joe Cocker, etc.

Do you have any good ideas for summer music to add to my playlist? Especially 60's and 70's music suggestions are welcome. Just leave a suggestion in the comments here.
