Well, you know what they say...if you remember the 70s you weren't really there.
Well, I remember the Acid I took at the Led Zeppelin concert in 1977 was in sugar cube form. Beyond that.. [Drum roll, cymbal crash.]
Good grief, some of things done in the 70s I would never do again. To understand it though, the context of the times also needs to be explained. In all seriousness, memories are still there. Sort of like finding them in an old box stored in the garage. You have to search for them. For example, the subject of John Lennon's "Mind Games" Quad record (fake) came up a few years ago and then a few years later again after that here. I recalled the story at different times, in different years. Then it occurred, was my recollection the same or different? Luckily, and strangely the stories matched, but one post from one year mentioned details that the other did not. One post told part of the story and the other post told the rest of the story without mentioning certain details from the other. But together, both posts tell a complete story.
Of course a good old, "if memory serves" can be helpful when trying to remember details that long ago..
