In the final scene of The Blues Brothers we see the band that is playing Jailhouse Rock in the jail's dining hall.
In the movie we see that the police is chasing only Jack and Elwood, not the entire band, so why is all the Blues Brothers Band jailed at the end of the movie?
I was wondering if the band is only a visitor, but as we can see they wear the prisoner uniform with relative prisoner number attached to the shirt.
