Many Happy Returns  Starting place?
Starting place?   EDEN
Friday, e.g.: ABBR.   SGT [from TV's 
Dragnet]
Suite spot?   HOTEL
Things used in semi circles   CBS [semi drivers use CB radios; I think they still do]
Tony's cousin   OBIE [I thought Soprano, etc. --- Tony is for Broadway shows; OBIE is for off-Broadway shows]
One you might not want to meet   MAKER [as in "meet your maker"]
House reporter?   CSPAN
Cult following?   URE
Taking badly?   ABDUCTION
Most clever theme:  Reversing the last word of an expression to create another one
"Honest, Professor..."   ALLEGEDPREP [alleged perp]
Pepe LePew...   DOUBLESTINK [double knits]
Visibly shaken king?   PALEREGAL [pale lager] 

"Me too!"   SOCANI  ["So can I" does not mean "me too."  The former suggests ability; the latter simply concurrence]
