Does remind me of how surprised I was (this being back in the my pre-internet days) when I picked up a vinyl copy of New Order's 1981-1982 (FACTUS8) EP and heard very different versions of those songs than I knew from 'Substance'. I've had disgusted looks from some hardcore NO fans over my expressing preference for the re-recordings.
I already had he Temptation 12"and FEP-313-1 (the Canadian version of FACTUS 8) so I was surprised that they had chosen to rerecord them. I prefer the 12" version of Temptation (with the commotion at the start when Hook put snow down the back of Sumner's shirt), but the Substance version of Confusion.
Maybe I should rephrase that to "Does have the chops, but very rarely displays them when singing live".
Unfortunately his live singing has always been patchy at best. However, by the BL era at least it wasn't likely to be due to having to be off his face to go onstage.
That said, I do rather like the raw, misbehaving sequencer on the 12" Temptation.
It's not a sequencer. It's the arpeggiator of the ARP Quadra being triggered from the DR-55 drum machine with the notes being played manually (basically like a live quantiser). That's why it 'misbehaves' occasionally - the wrong key on the Quadra is being pressed at the wrong time. You can see
Gillian playing it on the Quadra in the New York 81 early live performance of it (when it was still called Taboo No. 7).
Confusion is just shit in every version, the writing was very much on the wall Arthur Baker.
FTFY. Sumner in particular was embarrassed by the whole Confusion episode. Baker's M.O. was to use session musicians (at that time primarily John Robie) to knock out the music for a track based on the band's demo to make the best use of studio time. New Order didn't have anything written, and told him they weren't working with a session musician and that their writing process was basically jamming for weeks until they found something, so he booked them into a demo studio for two weeks but by the end of that they didn't have anything either. Sumner's takeaway from it was that they could come up with good stuff, but they weren't good enough musicians and couldn't do it at will.
