I never get sick of them
Paul's songwriting, his highly underrated guitar playing, the impressive ideas for songs, cerebral and artistic approach, Art's pure vocals and unorthodox harmonies- it gives and gives. Wonderful complexity there, enough to keep one's interest over the years. Every time I listen to them I hear something I haven't before.
At any time I can be taken by a set of musical acts, but time proves them. Many fall by the wayside while a few continue to provide peak entertainment value- S&G are that kind of act.
