This is a Queen recording of the Smile track, recorded at some time between 1971 and 1973, almost certainly featuring John Deacon on bass and not Barry Mitchell as some sources suggest. Musically it is similar to the Smile version, but some parts are slightly different. Freddie's vocals are more powerful than Tim Staffell's, and more suited to the track. The lyrics seem more ad-libbed by Freddie, and in places don't make much sense (such as the start of the second verse), but still this performance is much better than the Smile version.
Lyrics
Polar Bear
In a bright shop window sits a polar bear
Makes his eyes light up but I don't see him there
Among the tinsel he gives everyone a smile
See him as you'd see a star
Love her from where you are
He's not for, not for, not for sale
(Unknown lyric) walks a pretty girl
Someone like you've seen or by it's hard to tell
Oooh, and when you see her light seem around the lie
And see her as you'd see a star
Love her from where you are
Not for, not for, not for sale
And when the lights light up
To warn the grasping hand
Minor contentment wears a smile
Ooohhh-wahh
Not for, not for, not for sale
Not for sale
