Disco cover of the "Pinball Wizard" (by the Who)

Hello

Encouraged by the help I had in this forum while identifying a song from 70's (Brotherhood of Man - Lady Lay, 1974), I decided to ask another song from 70's to be identified.

This one is a disco cover of the famous tune of the Who called "Pinball Wizard" (live sample: http://www.youtube.com/watch?v=3SGqGbuGmJg)

Sung dominantly by female vocals, it was part of a medley like the medleys which "the Stars of 45" made. (Stars of 45 made many covers from 70's songs but not this one) The female vocals of this song are similar to vocals in http://www.youtube.com/watch?v=XArBdFvVZss (the Spanish girls band "Acuario")

I've done a search on YouTube but had no luck finding it. Actually, it 's quite unlikely to be found in UTube because you know, 70's disco songs are rarely uploaded in UTube so finding the audio/video clip of this particular song will be much harder, if not impossible.

This could be by the pop trio "Tight Fit" In 1982 they made a medley with the song therein.

Unfortunately i didn't found the medley to prove. But their style is similar to Stars on 45
Listen here to another medley they made one year before:

It's quite possible that "Tight Fit" might have sung the song I 'm trying to identify because yes they have Pinball Wizard in their repertoire. But whether their cover is the one I'm talking about or not, I liked this Tight Fit medley. They made it quite successfully. I'm a fan of the Hollies too and they covered Hollies very fine. I liked it.
