This is the song which plays at the end of the show, when Luke interrupts Jess to knock a hole in his apartment wall. The song has been used before in the show, but the original version by Louis Armstrong, previously discussed.
This version is sung by Joey Ramone, former lead singer of punk band The Ramones, from his debut album as a solo artist, Don’t Worry About Me. It was released in February 2002, not long before this episode aired. (The music video for “What a Wonderful World” was directed by Debbie Harry from Blondie).
It was released posthumously, Joey Ramone having died in April 2001. The album peaked at #21 in the US, and was warmly reviewed.
Notice that this episode ends with an allusion to Mayberry, an idyllic fictional town, “It’s a Small World”, and “What a Wonderful World”, to impress on us the perfection of this little world they have created for us.
