Possible Title: 
Two Against OneGood Ones:Handle for a razor   ATRA
Lay back?   ETTE
Nice approval   BON
I enjoyed the challenge of this toughie.
By the Way:Dick Van Patten’s 
Mama role   NELS [“…and big brother, NELS” still echoes in my ears 60 years after my neighbor who had a TV let me watch with them.  Thanks, gentlemen, for the memory.]
Who knew?:NED Washington wrote “Stella By Starlight” --- and I like that song, especially by Vic Damone.
Crossing OGLALA with CHASSE and WEIL, clued by 
The Need for Roots is unsporting.  I feel this way mostly because it beat me. 
Some Nits to Pick:Terrestrial wiggler   EFT [these newts have feet and run, so unless one believes it possible to w(r)iggle on feet (which I do not), “Terrestrial crawler” would be a better clue.] 
RATING:   
 
  
 Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
