Well, I can give you three to kick off with.
First, Vivaldi's guitar concerto in D major II: Largo. When I was VERY young my mum bought me a tape player/recorder, one of those top loading portable ones that was the size of a cereal packet. Anyway, I had a few tapes of those very dark central European fairy tales and I'd listen to them constantly. Each story was preceded by this piece of music. I never found out what it was for thirty five years.
Second, and from the same era, Benny Hill's Ernie (The Fastest Milkman In The West) Around the time this song was number one in the UK the unions ran the place, and they would, in support of such reasonable demands as twenty-five percent pay rises, regularly turn off the power. My dad would hitch up a black and white portable TV to a car battery and we'd watch it by candlelight huddled under sleeping bags. Imagine perhaps, I dunno... Scotland on Friday morning.
Anyhoo, as the battery ran out the picture would get smaller. One of my earliest memories was watching this as the end of TOTP with a picture the size of a postage stamp.
On the face of it this song is a silly comedy record. In fact, in my opinion it is one of the very finest lyrics ever committed to vinyl. It's fiendishly clever.
Finally, a very, very personal one. We all have someone who got away, don't we? Mine was a Scottish girl. It truth it still is. Don't tell the girlfriend.
We split, then three years later she turned up again on my doorstep but with a severe mental issue. The lyric to this song really says everything about the ultimately unsuccessful struggle it was to keep her on track. I think of her every time I hear it.
"You are only coming through in waves / Your lips move, but I can't hear what your saying."
