@zabadak - it's long been held that this is the shortest UK #1 hit, which I'm fairly sure is correct. Poor Me is about ten seconds longer (comparing remastered CD versions of the tracks, anyway).
Re: Adam Faith's vocal delivery, forget his lisping, he sounds borderline Oriental in parts of this!
Yes, these records do sound rather dated today, perhaps why this one was used in a slightly surreal opening segment of the soap Hollyoaks a few years ago, accompanying a female character dusting her house like a typical 1950s housewife.
"Don't turn awound 'cos I'll be missing" ... invites a thread to those singers that every now and then betrayed a slight (and appealing) lisp (Sinatra included). IMO, listening to assorted newscasters on TV and Radio, this mild speech defect adds indelibly to a woman's allure.
Coincidence seeing this posted today as I have just been reading the Mojo obituary for John Barry who sadly died on 30 January. It quotes Barry as after the sessions he got a call from Norman Newell (Head of EMI) telling him that it was the worst record he'd ever heard. Newell called him again a few weeks later to congratulate him on being number 1!
It must be.
It looks like the Phillips group may have pressed some copies (the three pronged centres). Perhaps EMI had to get their help to keep up with demand. I understand that in the USA RCA used to get Capitol to press Elvis releases as RCA couldn't cope. I've only ever seen this Parlophone record with the three pronged centres.
