Lead Sound for "Hot Stuff" by Donna Summer

I’m working on the synth lead sound for “Hot Stuff” by Donna Summer and for some reason I’m just not getting it. Either I’m not choosing the right plugin (or plugins) or I’m just hitting a brick wall. I have a VERY wide array of plugins to choose from.

Are any of you playing this song, and if so, how did you approach this lead sound?

Also, I ‘think’ I hear a guitar doubling the lead line an octave down, but would be interested in other opinions.

thanks,
