Blues Brothers at Bob's Country Bunker

I just watched the original Blue's Brothers movie - probably for the 15th time - and I noticed (not for the first time) that when the Blues Brothers' band plays at Bob's Country Bunker that the first song they played is Raw Hide, and then they played Stand by Your Man. Then we skip ahead to the last song, and it's Raw Hide again. So I wonder: Did they only play 2 songs the whole time they played, or where there other songs in-between, and if so, what were they? Is it entirely possible that the Blues Brothers only knew 2 country songs, and that they only played those 2 the entire hour or two that they were there?

I think it skips time and then they reuse Rawhide for the close because it's popular.

I'd say the joke is the only two country songs the Blues Brothers know are Stand By Your Man and Rawhide, so they played those over and over.
