Here's another frame card using images from the Graphics Fairy:
"Dance To Your Own Tune"
There are two sets of can can dancers next to each other to make the line longer. The showgirl isn't interested in the can can (I love the way she looks the other way, and is leaning against the bar having just ordered another shot!). She prefers to wait for her own song to play.
The theatre is decoupaged from two layers to add some depth. The musicians in the orchestra pit have just their heads & instruments in the upper layer. The backgrounds from the circles & the stage curtains have also been removed in the upper layer.
The background is just some plain red card with barn door & dusty concord ink sponged on in "clouds" for atmosphere.
