August 1969 doesn't really improve on the year before, according to Wikipedia: The Manson family did their murderous thing in LA while British troops were deployed in Northern Ireland after the Battle of the Bogside.
In music news, Woodstock Festival happened and the Beatles were photographed crossing a road in North London.
In space, Mariner 7 was checking out Mars, Americans had landed on the moon, and on another planet in another solar system, this was going down...
There's a CD of the music to The Clangers by the late, great, Vernon Elliott. If you haven't watched The Clangers (1969/72 episodes only, thank you) or Ivor The Engine, then you are excused for an hour or two while you edificate yourself.
Fairport Convention - Who Knows Where The Time Goes
Sandy Denny who wrote and sings this song is the female singer on Led Zep's 'Battle of Evermore'. She left Fairport Convention at the end of 1969, rejoined for a while in 1974 and they never had another female singer. This is a classic in the folk world and has been covered relentlessly. Fairport Convention also gave us Richard Thompson, we'll get to him another day.
Grateful Dead - St. Stephen
My all-time favourite Grateful Dead song from the rather odd 'Aoxomoxoa'. There's some classics ('China Cat Sunflower'), and some utterly incomprehensible waffle ('What's Become of The Baby'). This song has everything in one compact package. Beautiful Garcia guitar work, impenetrable lyrics, a slow bit, a fast bit, and the howl at the end of the first verse.
Creedence Clearwater Revival - Graveyard Train
For that mournful riff. Creedence were a studio creation of a New York boy and his brother. They didn't have a southern bone in their bodies but they conjured up the mythical south like no-one else before. What was also impressive was they had hits with political songs. When Fogerty finally won his lawsuit and started playing CCR songs again, it was a wonderful sight to see.
Blind Faith - Can't Find My Way Home
I seem to have skipped Cream, but Blind Faith were an improvement on that band, due to the presence of Steve Winwood, who could push Clapton melodically and write a damn fine song, such as this one.
David Bowie - Space Oddity
The first pop video I remember, although I was only three so obviously not from the first time around. It was a couple more years before this became a hit, and got a different video that was nowhere near as disturbing. I think I remember this because I found it really freaky, in that it emphasises Major Tom's hallucinations and suicide. A nice cheery one to end on.

The rules are to be interpreted as you like really, but are something like this:
Pick years from when you were born to now. It really doesn't have to be all of them
Feature some songs from one of those years in a post with some details about why you like them. You can write something about the year in general too.
