just check this site's page for both movies. the song is told in the "Music" section of both pages. song's title is "It's Been a Long, Long Time".

Yep I knew that song when I heard it the first time. I think it was a wonderful nod to that movie. Plus it seems to be the appropriate song for them to dance to

Yes.

Yeah i noticed that. love that detail.

Yep, noticed it. Even when I saw Endgame for the first time in theaters, I knew that the song playing at the end was familiar. On the next time I rewatched WS, I immediately knew why.

Also used in the (amazing) opening sequence of Loki finale

The fact that the song was used as the opening to the season finale of Loki s1 is a big part of why I believe that the original branches of the temporal multiverse were caused by Steve staying with Peggy.

Nah, kang allowed steve to do that so it couldn’t be a threat

hot

Yes
