Can anyone tell me what the British sitcom/comedy was that played the lakme duet in its theme tune

Hi,

Odd one I know, but roughly around the mid to late 80's in the UK, there was a TV series that played the song from lakme duet in it (or its own version).

I cannot find it anywhere apart from a load of British Airways adds....

Not sure if anyone can help with this, but it's been driving me mad for years. So would be greatly appreciated if anyone knows or has the resources to find out.

Many thanks in advance
