Isn't She Lovely by Stevie Wonder is featured in Prom Queen, the twentieth episode of Season Two. It is sung by Artie with New Directions Boys (except Kurt) as back-up.
It is performed in the Home Economics Room, as Artie serenades Brittany during her class as a way of apologizing for calling her stupid and asking her to the prom. Despite this, she turns down his invitation for them to go to prom together. Kurt is delighted to hear this performance due to the fact that it's a prom proposal.
Artie:
Isn't she lovely?
Isn't she wonderful?
Isn't she precious?
Less than one minute old,
I never thought through love we'd be
Making one as lovely as she,
But isn't she lovely made from love?
Isn't she pretty?
Truly the angel's best;
Boy, I'm so happy.
We have been heaven blessed.
I can't believe what God has done;
Through us, he's given life to one.
But isn't she lovely made from love?
Artie with ND Boys:
Isn't she lovely?
Life and love are the same.
Life is Aisha,
The meaning of her name.
Londie, it could have not been done
Without you who conceived the one
That's so very lovely made from love.
