When did the final episode of How I Met Your Mother air?
Last Forever
"Heaven" by The Walkmen features in the final scene of "Last Forever". Gowan said that "it seemed like it was written for our show". Gowan had suggested the song before, especially for use in the season 8 premiere, and said that when he pitched it for use in the season 9 finale, "[the song] was just the one that resonated with all of us the most".[19]
