Yes, on the His'n'Hers tour it was played in Manchester (end of April '94 I think). A bootleg exists and I've tried to upload the performance to the yahoo account on a couple of occassions before to no success (think the file was over the size limit). The sound quality isn't fantastic but it's intriguing to hear.
Russell's violin playing in the chorus is boss, he has kind of an arpeggiated echo-effect going on which would have sounded great on the album.
A shame it wasn't performed more, it (or the other tracks on the Sisters EP) should have made the album.
Sorry, it was the Kentish Town Forum in London where they played it in May '94 (I was thinking of the fellow-rarely played live David's Last Summer live debut in Manc the week before). Apparently Seconds' live debut was a year earlier according to Will's Wiki.
Anyway, I just tried sending it to the yahoo account but it wouldn't send from my yahoo address and then tried with gmail and at the second attempt it worked! Enjoy. Classic Cocker pre-song introductory waffle at the start too.
