Kirk's door buzzed.  "Come," he said.

"What are you doing still up?" McCoy asked in an accusing tone as he marched into Kirk's quarters.

"What are you doing still up, Doctor?" Kirk asked in reply, not taking his eyes from his computer screen.

McCoy rolled his eyes to the ceiling and mumbled, "Why must everyone mock me?"  He glared at Kirk.  "I'm making sure my patients sleep!"

Kirk chuckled and turned to face the doctor, who'd perched himself on the corner of Kirk's desk.  "Don't worry, Bones, I'm almost done."

"Doing what?" McCoy stood and walked around the desk to join Kirk in looking at the screen.

"Planning shore leave."

McCoy scanned the words.  "With rolling stones?" he asked incredulously.  "I'm not putting you back to together again, Jim, I'm having enough trouble with…"

"No," Kirk answered, chuckling again.  Nothing like the good doctor's ignorant assumptions to put him in a good mood.  "I don't believe there'll be any Rolling Stones.  I just ruled them out."

"What instead?"  McCoy was suspicious.

Kirk barely hid a smirk.  "Beatles."

"Beetles?!? Jim, what…"

"No, come to think of it, no Beatles, either.  Bones, help me think…"

"Of what?  Do you have monkeys?"  McCoy's words dripped with sarcasm.

Kirk was out right laughing.  "No Monkees, Bones, this is serious."

"You're laughing!!!" McCoy shouted, frustrated.

"Because you have no idea what I'm talking about."

"Finally, something we can agree on!"

Kirk stifled his laughing and grew serious.  "I'm looking for a song.  The Rolling Stones were a band on the mid to late twentieth century."

"Beetles?"

"Yes, Beatles.  Monkees too."

"Why the twentieth century/"

"Spock said that Lieutenant Montgomery had a preoccupation with music of that era.":

"Spock said…why, Jim!  Is our Vulcan stooping to gossip?"

Kirk shook his head.  "It was of his evidence…"
"What evidence?"

"For his conclusion…"

"What conclusion?"

"That Lieutenant Montgomery was suicidal."

McCoy shook his head.  "How is her preference in music evidence for…that?"  He couldn't bring himself to say it.  In his career, he'd seen people die in agony of things too terrible to remember.  It was hard for him to accept that someone would purposely do such to themselves for any reason.  Kirk was speaking again.

"Spock found a song in Lexxi's head when he melded with her.  It was called, 'I Am A Rock' by…"

"Simon and Garfunkel."

"Yes, how did you know?"

McCoy sighed.  "I heard two songs by them.  Lexxi's doing."

"You mean, 'Hello, darkness…"
"Exactly.  'The Sound Of Silence.'  And 'Flowers Never Bend With The Rainfall.'"

"'Flowers Never Bend…'  Such strange titles."

"I know.  Hey, I don't know what this song is for, but if it has anything to do with our mysterious Lieutenant Montgomery, try these people."

"Thank, Bones."

"And get some sleep!" McCoy called over his shoulder as he left.
