This is not the only one of my parents' favourite bands that put out a song in 1987 that became my favourite by them, it's just weird that it happened at least two other times. With Pink Floyd and Learning to Fly and On the Turning Away from A Momentary Lapse of Reason and Moody Blues with Your Wildest Dreams from The Other Side of Life. Fleetwood Mac had some good songs around that same time, but Rumours from 1978 is their best album, so they don't count.
Not sure if they were all in 1987 but around that time, 1986-1988 was just an awesome time for music. Before grunge, after New Wave, you had the 60s and 70s bands mostly still around and showing the younger cats how it's done, and you had newer bands (for the time) that would go on to become classics in their own right.
I never really got into Grateful Dead. I was never a hippie, never got into smoking weed and certainly not other recreational drugs. It was just never my scene. I always heard the Grateful Dead suck, but you go for the vibes and the community. To their shows, I mean. From "Shakedown Street," named after one of their albums, the little pop-up markets that spring up outside their shows, to the shows themselves, you weren't there because the music was particularly good, you were there because of the like-minded individuals. I missed that whole scene by a decade or two, and I'm not sure I would have fit in there anyway. Like Woodstock in the US and similar concerts that were more like "events" — OzzFest would be the more modern version, I think.
That said, I always liked Touch of Grey and it always makes me happy to hear it. I hope you (especially if you've never heard it before) get a similar vibe. There are some inspirational stories around it in the comments of the video. I think some of those are made up, but you never know. I could be making shit up in these "song of the day" posts. You never know. I'm not, but can you trust me? Maybe you don't care, we're all just here to enjoy the music. I post what I like. Sometimes I have a story, sometimes I have other random shit to say, like today. I hope others post as well, about the music that moves them, or just post the music that moves you and say something else, doesn't really matter. And this "just be" kind of attitude? I think it's the same kinda thing the Dead were laying down in the 1960s. So maybe I am actually a part of it, in my own way. Maybe you are, too. If not, that's cool too.
