This is one I learned when the record first came out. Single-handedly as a teenager just banging on acoustic guitar.
Played it thousands of times, usually for myself to warm up.
Different every time, and still haven't sounded very much like Pink Floyd yet ;)
Still most people have never heard me do it ever.
There's not that many Floyd tunes that are so great without a band of some kind anyway. That's my story and I'm sticking to it ;)
I'm not an active musician or songwriter at all and when I do play for people intentionally it would usually be things that are more familiar.
But every now and then somebody will hand me a guitar or just say "play us something". They know it's going to be oldies :)
In the right situation as I accept I sometimes answer with the simple question; "Childhood's End?"
Without allowing enough time for a response then I just start banging. I already saw the look in their eye.
This is a tune that keeps giving and I'm trying to give them what it's giving you :)
