I think Fiedler was the last great pops conductor. He conducted classical pieces well, and he seemed to have a sense of humor and a sense of style with pop material. I think rather poorly of the current crop, especially the one with the NY Pops who seems more interested in speeding through whatever he's conducting so he can spend more time schmoozing with the audience.
I didn't have many Fiedler albums; my first memory of hearing a Boston Pops recording was around 1963 when I fell in love with Friedler's recording of the Beatles "I Want to Hold Your Hand," which I promptly purchased as a 45 and played to death.
