Was this song released as single? If so, was it an A side or B side? And what other song was included with it? Also, is it was a single, what number single was it from A Day At the Races (i.e. Somebody to Love was the lead single, while Good Old Fashioned Lover Boy was the fourth)?
Is it just a grand piano that plays the opening chords? Maybe it's just me, but it doens't have the same sound that other songs on DATR that use the piano do, making me think it is something other than just a grand piano.
What language is the song Mustapha in? Are Mustapha and Teo Torriatte the only Queen songs in a language other than English?
EDIT: In the liner notes of the album, it says that both a harmonium and a plastic piano are used in the song. Do you know where each is used within the song?
There's Freddie with La Japonaise and Ensueno, and Brian sang a verse of TMLWKY in different languages sometimes, like German on a german TV appearance ("Zu viel Liebe tötet, sie erlaubt kein Doppelspiel..."etc.).
I haven't heard "Another World (Spanish)" here: link but it could be what you ask for. And "Foreign versions" in Real Audio here: link . Probably someone else knows more.
And if it counts at all, in Dancer you find a line in German: "Guten Morgen, Sie wünschten geweckt zu werden." It's a hotel wake-up call, that you get automatically from a computer, and it roughly means "Good morning, you asked us to wake you up." But it's of course not a band member saying this. :-))
Then you might want to have a look at link and if you want to be picky, it is Toriatte (look at the single cover) with only one r. But anyway, it's a good review, and maybe you try to get Brian's opinion or comment via his website. You never know, he might reply. :-) Video here: link
