This is Karen Young performing Hot Shot. I remember Vince Aletti describing certain disco discs (that's how they called 12 inch mixes back then) as "hot, hot, hot". That description seems to fit this little spicy number especially well.
And I gotta admit I love the sassy expression of womanly lust, finding it rather liberating and simply fun.
This was BTW sampled by Daft Punk.
Have a good week everyone,
