I have adopted the "finger in the ear" technique lately

It was during the recent "Daughters of Albion" concert. I also found that the beneficial effect was enhanced by putting a finger in each ear.

I'm sure Ewan MacColl would strongly agree with this improvement to his style.

The critics of MacColl on this forum, would probably find that *removing* their finger's from their arsehole's would improve brain function...Ake
