Does Anyone Know Anything About How Jeff and Tony Got Along Off-set?

-All i know is the two were supposed to be best friends on the show; to make that believable it can be assumed the two hung out off-set and got tight.

[episode referred to: Ten Percent Solution, the one where Bobby quits acting to manage Tony who has decided to be an actor. The final dialogue between the two leads to laughter and an embrace that seemed sincere.]

-Apparently, when Conaway decided to leave the show the cast was caught off guard and got hurt. Marilu Henner said they were real close as a unit, the cast that is.

[episode referred to: Bobby Doesn't Live Here Anymore, if you notice one scene where Bobby and Tony have a row, it seems authentic]

-I remember reading somewhere that Tony Danza, & Marilu Henner were at the bedside of Jeff Conaway. This was right around when he died. That says something, but I wish there were more details or stories of the two... in any light
