So some people feel the need to improve their performances by the use of drugs, etc. I've seen it happen. Jefferson Whatsit, they used to disappear and return talking very loudly and playing like demons. Lots of other people worked the same way. Me, I know I work better after a pint of beer -but I've got to say that the best inducement I've found to a good performance is to get through the first three numbers without mishap.
