What the fudging heck is the song 'Set Adrift on Memory Bliss' about?

[OldFred]

Just heard this on spotify.
Loved it back in the days and still do, but can anyone tell me what's the meaning behind the lyrics?!

Any other baffling songs you can't make head or tail of?

Ooh what have I missed! 🤔

I think he goes for a drink in a bar and sees an ex who's now married and wonders what might have been?

I still have no idea but I loved it back in the day (old gimmer alert) and it's still a belter of a tune

The clue is in this line:

Reality used to be a friend of mine

The narrator has lost touch with reality and is rambling in a dreamlike state about his past relationships; as with a dream, it doesn't always make sense.

Laughing at old gimmer alert 😂

Funny how many songs you sing along to, but actually have no idea what any of it means.
