Yep, Neither Dave nor Adrian (too bad
)are included among the backing vocalists for the track, and they're not even visible on the massive front cover picture. Though you can see a stampsize picture of them on the backcover of the vynil plus another one where they chat with Eric Bloom from Blue Oyster Cult, if my memories are accurate. But I only own the CD these days, where that picture has been removed, and the other ones are so small or cut from the waist down that it's sometimes hard to say who's who.
I think I reckon they did say once they only showed up to do their guitar parts and then left immediately. Buth they were right in the middle of the world Slavery tour back then (20 & 21 may 1985), having to be back in Maine,for a gig on the 23 rd.
Still, this track is an outstanding one, really catchy and would have well deserved to reach another status than just being a cult song. I remember that here in France, no radio station would play it. "Stars" was once said to be broadcasted in the next 30 minutes on a parisian FM. I waited for an hour, and nothing happened....
