Narrative:
Bna tower cleared air carrier into 'position and hold' on runway 20R. We took position accomplished our final checklist items and waited. I supposed the delay in takeoff was for IFR release into mem. First officer said, 'I hope that guy is landing on the center'. I had no idea what he was talking about and I looked to the left searching for an aircraft on final for the center. Tower abruptly and hurriedly said, 'air carrier Y, go around'. Our TCASII indicated plus 200 for air carrier Y, he passed slightly off our right during his go around. Tower apologized to air carrier Y for the go around and he said he became involved with something else and forgot about the air carrier X on the runway. It turns out that my first officer saw the TCASII target from plus 700 ft on down but his comment was a hint and a hope rather than something clear. He didn't mention TCASII and I never thought to look at it while sitting on the ground. TCASII voice warnings are suppressed in that position. In retrospect, I wish I had questioned the delay but delay in position is not uncommon. Air carrier Y said he saw us. It's interesting that 2 people in air carrier Y and 1 in air carrier X saw the problem but chose not to speak up on the radio.

Title: CTLR FORGOT ACR X IN POS ON RWY WITH ACR Y CLRED TO LAND SAME RWY. ACR Y ISSUED A GAR. ACR X AND Y HAD TCASII TA.
Narrative: BNA TWR CLRED ACR INTO 'POS AND HOLD' ON RWY 20R. WE TOOK POS ACCOMPLISHED OUR FINAL CHKLIST ITEMS AND WAITED. I SUPPOSED THE DELAY IN TKOF WAS FOR IFR RELEASE INTO MEM. FO SAID, 'I HOPE THAT GUY IS LNDG ON THE CTR'. I HAD NO IDEA WHAT HE WAS TALKING ABOUT AND I LOOKED TO THE L SEARCHING FOR AN ACFT ON FINAL FOR THE CTR. TWR ABRUPTLY AND HURRIEDLY SAID, 'ACR Y, GAR'. OUR TCASII INDICATED PLUS 200 FOR ACR Y, HE PASSED SLIGHTLY OFF OUR R DURING HIS GAR. TWR APOLOGIZED TO ACR Y FOR THE GAR AND HE SAID HE BECAME INVOLVED WITH SOMETHING ELSE AND FORGOT ABOUT THE ACR X ON THE RWY. IT TURNS OUT THAT MY FO SAW THE TCASII TARGET FROM PLUS 700 FT ON DOWN BUT HIS COMMENT WAS A HINT AND A HOPE RATHER THAN SOMETHING CLR. HE DIDN'T MENTION TCASII AND I NEVER THOUGHT TO LOOK AT IT WHILE SITTING ON THE GND. TCASII VOICE WARNINGS ARE SUPPRESSED IN THAT POS. IN RETROSPECT, I WISH I HAD QUESTIONED THE DELAY BUT DELAY IN POS IS NOT UNCOMMON. ACR Y SAID HE SAW US. IT'S INTERESTING THAT 2 PEOPLE IN ACR Y AND 1 IN ACR X SAW THE PROBLEM BUT CHOSE NOT TO SPEAK UP ON THE RADIO.
