For He's a Jolly Good Fellow

"For He's a Jolly Good Fellow" is a Human song that people sing during commemorative events for an individual. It was sung when Benjamin Sisko was promoted from commander to captain in late 2371 and to Chief O'Brien on his birthday in 2373. 

In an alternate reality, the crew of the USS Enterprise'' (NCC-1701-D) sang "For He's a Jolly Good Fellow" in Klingonese for Worf at his surprise birthday party in 2370. Counselor Deanna Troi translated it, but had problems as there was "no Klingon word for "jolly"."''

It was also sung to Kes on her ninth birthday in 2378 in the alternate timeline she experienced.
