reversed songs

I felt like it's possible, but now I know it for sure: the intro of Susumu Hirasawa's 'Parade' is a reversed line from another song. People who know it are saying it's from 'Nurse Cafe'. I couldn't sit still and checked it by playing the song in reverse. It's really similar, though not absolutely authentic.

Speaking of reversed lines, there was one song that bothered me, but now that I've checked it, this case is not as interesting.  The song is 'Niji' - 虹 (A DAY IN JAPAN Version) - by Denki Groove where the intro is obviously a musical phrase turned backwards, but this part is simply the last lines of the chorus sung only by the girl.
くりかえす事もタマにある　ぼんやりとただ意味なく
遠く短い光から　水のしずくハネかえる
ゆっくり消える虹みたく トリコじかけになる
