I don't get the Sheeron phenomena either but no doubt many said the same about Bob Dillon initially.

I consider myself very lucky that bands ruled when I were a lad and it was easy, and cheap, to watch live music any night of the week anywhere in Cardiff. Not so these days.

Whatever genre a youngster gets into, he/she does because others do too and with there being relatively few bands and decent music atm, IMO, Sheeron seems to have arrived at just the right time.... for him!

As for Elvis Costello, seen him a number of times at different stages in his career and is a top writer and performer.
