Bolloxs Greg - playing the age card is a red herring. A session historically has been a gathering of tune smiths and it is only recently that it has included singing. I've been involved in trad music for 45 years and my father before me and a sesion has always (in terms of me and my dad which would be about 90 years) been about tunes. Having said that I repeat that I (for one) accept the change in the meaning and advise pp to do he same. In the words of Chinua Achebie "Things fall apart".
