This might be more in the Medium - Medium/Advanced category but:

Several years ago did this arrangement of Blues for an Autumn Night with an advanced group of 8th grade saxes I had.
Not sure how to get the arrangement now as the link below takes you to a UK website ... but maybe you have other options.

I haven't tried the other titles in the series but it might be worth a look.

Good luck!
