Sugwash,favorite singers are always a matter of subjectivity,there are several singers I dislike but that doesnt make them bad singers.
if someone doesnt like a performer it is not prejudice[prejudging]its
a matter of taste,if we all liked the same thing,life would be pretty dull.[but if his diction is bad then technically he is a bad singer]
There are people out there who dont like me and people that do.I dont lose any sleep over it,and im sure Seth Lakeman doesnt either,all the time people are talking about him its giving him publicity.
Iwould rather listen to Jeannie Robertson,or Sonny Boy Williamson Tony Rose, Nic jones ,or Carthy,Each to their own.
