I know people on here hate David Gray, but he's already done an extremely good cover of Soft Cell's 'Say Hello, Wave Goodbye' that would render any Moz version redundant, as it's slowed down and stripped to a very Morrissey style already.
My musical guilty pleasure is Del Amitri, and I've always thought Moz would do a brilliant cover of 'Spit In The Rain'; even the title sounds like his and the guitars would suit Boz's rockabilly playing. I also reckon Moz could inject the right amount of passion and venom into it that Del Amitri couldn't achieve.
C'mon Moz, make my day, play it on your next tour:
You can grin but you can’t hide
All the emptiness inside
Since she left you like spit in the rain
Without doubt it is true
She was the only love you knew
Now she’s gone it fades away
Like spit in the rain
And you can try to find her
But you’ll be looking in vain
Because love disappears like spit in the rain
You can try to figure out
Why you mean nothing to her now
But you might just as well
Just go spit in the rain
Maybe then you will find
Her sweet memory in your mind
Washed away, out of sight
Like spit in the rain
Without doubt it is true
Without her there’s only you
But with a little luck and a little time
You’ll pull through
