There are many different routines for C&B and they are usually available via on-line suppliers. How much comely is involved depends on the performer but C&B can be done without words as well. Many years ago we saw on the Paul Daniels TV Show a young Indian boy doing C&B with full patter but in his local dialect which few could understand. It didn't matter as the routine explained itself as he went along and his 'sing-song' accompaniment just made things all that more enjoyable.
