Neither have been released as instrumentals in any official form.
You'd think Bijou, which only has like 5 lines, would have been edited that way at one point, but no, engineers got it into their heads that the lyrics had to stay on the LP edition and the Hints Of Innuendo promo. The eYe is the first portion of the song before the lyrics come in.
It's funny that the lyrics keep surviving, since the track written as a sort of inverted song, with guitar replacing lyrics and lyrics replacing the guitar solo, as it were. By editing all the guitar and keeping the lyrics, the engineers are essentially removing the "lyrics" and keeping the solo. Obviously ,they didn't get the point of the how the song was written, haha.
