??? 1990's remake???

I'm sure I remember watching a one off special in the 90's of It Ain't Half Hot Mum. It was either a film, or a tv special, or a programme about "the making of" it... (and I think it was screened on ITV1, then called ITV) but it was definitely newly made, and all acted and not a documentary with show clips...

Does anyone know what this was??

And did it star Simon Baker/Simon Denny/Simon Baker-Denny (when he was Australian, not the American in The Mentalist!!) I hadn't thought about it until I saw the Mentalist advert!

thanks to anyone who can help!
