Wow - that's a tough one. Both songs are from another era/sensibility and would have a hard time fitting in with more contemporary material. All of our band-members contribute material to our set-list and usually the drummer is the most critical. (can't live w/o them, can't shoot them

) Would your typical audience
like songs like those two? If so I guess you could arrange them in a more contemporary/palatable way.
I was searching for French Yeh-Yeh songs from the late '60s and stumbled on this - very old school 'euro' anthemic (and not French!) but could be fun to play. Only using it as an example of outdated material that would still be musical enough to be entertaining to an audience.
