1061 Yes - Yours Is No Disgrace
In my opinion Yes is one of the better specimens among Prog/Rock bands of the '70s. It seems as if they never tire when performing; it seems like most pop acts usually can't keep it up past the magical 2:00-3:00 mark in a song either strictured by themselves or the record company. Whatever the case, much of the time I'll take the 10+ minutes of musical bliss over the 2:30 minute musical quickie.
