Sony/Legacy C2K 46973.
I have mixed feelings of this 2-CD set from Columbia. On the one hand, the track selection is strong. It includes most of the B-sides, the non-LP singles Foxy Foxy and Saturday Gigs (though this is an alternate version, with Mick Ronson on synth), the previously-unreleased Henry And The H-Bomb and Lounge Lizard, and the "uncensored" version of Through The Looking Glass (with an explosion of very bad language at the end). Sound quality is OK (but not the best).
But why did they include the four Island/Atlantic tracks? Why didn't they include the B-side version of One Of The Boys? Why have we been given the LP version of Roll Away The Stone (again), when the single version is (a) stronger, and (b) was Mott's biggest-selling UK single? Why is there no live material (excepting Ian Hunter's brilliant interpretation of the classic American Pie, recorded live at Uris). Why such a lame cover? The sleeve-notes seem, on the face of it, to be good, but they concentrate on Ian too much - weren't Mott supposed to be a band?
Note that Lounge Lizard has since been made available on other releases, but Henry And The H-Bomb, the "synth" version of Saturday Gigs and "uncensored" version of Through The Looking Glass are still (in 2018) unavailable anywhere else.
