The best one was All America alien Boy which Mick Ronson ( guitarist from Mott the Hoople) did not play on and consequently most critics thought the album wouldn't be much good. how wrong they were!
The best song is You nearly did me in. Yes Freddie Mercury and Brian May did backing vocals.
The title song is a real rocker
Ian Hunter is apparently one real rocker live. I believe he is around 73-75 now.
