Sorry dude, how can it be unreleased if its on a record? The single reached number 4 on the US billboard and number one on the Billboard adult contemporary chart and as the second single taken from the Invisible Touch Album. Single released in October '86 in the US. June '87 ib UK.

The US 7 inch single had two tracks. The second being an edited version of the instrumental track do the neurotic. UK version had a different track.

Bands often used to release instrumental versions or remixes of songs as the B sides. It may not be your taste, but many find them relaxing or chill out music.

Genesis often did instrumental tracks in their prog rock time. The band loved the song but only played it live a few times. Some even wish it was on the album instead of The Brazilian, which was another instrumental track.

It's very popular among Genesis fans.
