See Emily Play" was the Pink Floyd 1967 top 10 UK hit.

Yes, that’s the one.

After their debut single “Arnold Layne” (which only reached #20), “See Emily Play” hit #6 in the UK in June 1967. It was written by Syd Barrett and recorded at Sound Techniques Studios in London. The song’s psychedelic sound and whimsical lyrics captured the summer of love perfectly.

It’s often confused with “The Scarecrow” or “Astronomy Domine,” but “See Emily Play” is the single that broke them into the top 10. If you haven’t heard it, it’s worth a listen—still sounds fresh.
