How long can a Kenku remember particular sounds/sequences for? Could a Kenku bard reproduce performances by others years later? What about combining the sounds of multiple instruments/voice? Multiple noises would be hard – would recommend a Intelligence (Perform) check to get it right. IIRC a kenku has near perfect recall of noises, so can dreg up stuff from decades ago if needed.
