Sonny Garrish, Sonny Burnette, Weldon Myrick, Paul Franklin, Buddy Emmons, (Inventor of the Emmons pedal steel,) Hal Rugg, "Sneaky" Pete Kleinlow, Lloyd Green, Buddy Merrill and Pete Wade are among my favorite steel players, and I can usually tell which is which when listening to the background instrumentation in somebody's song.
EDIT: Isn't it funny? I just noticed there are two Buddys, two Petes and two Sonnys here.
I have many steel albums, one from Lloyd Green, one from Buddy Merrill, one from Buddy Emmons, who plays a haunting 6-minute rendition of Pachelbel's Canon in D Major on a STEEL GUITAR, absolutely awesome and available on iTunes, believe it or not, (Nothing Was Delivered, a Bob Dylan song, is found on that album as well...,) Sonny Garrish had a great solo album in the '70s, and Sonny Burnette, Hal Rugg and Weldon Myrick all got together and made an album called Steel Players of the Grand Ole Opry, with a classic version of "Killing Me Softly" on there.
And speaking of Bob Dylan, Pete Wade was the steel player on "Lay Lady Lay." He has a steel guitar version of that song on a 45, of which I have an old, scratchy copy.
Then there's The Eagles. Bernie Leadon played steel on My Man, Ol' 55, Lyin' Eyes and Best Of My Love.
Too much information about steel players, or shall I go on...?
