Just an idea!!!

[moses]

Iona - The Flight of the Wild Goose (Instrumental)

is correct.

1. Water, water everywhere - Pink Floyd - Echoes - Albatross
2. Off the wall
3. Holy Spirit wings - Iona - The Flight of the Wild Goose (Instrumental)
4. A royal whim
5. She's your sister? - Yes - Starship Trooper - Bluebird

Since we seem to need hints, here goes:

They're both British bands, both from the 70's, both pretty well known, both still around today (with a few different members).

2. Was intentionally misleading, it has to do with the lyrics in the song... so maybe it's not OFF the wall, but...

4. Royalty has to do with the band's name, the whim has to do with the bird.
