Avengers Endgame opens with 1967’s Dear Mr Fantasy by Traffic over the Marvel Studios logo.
We then see Nebula and Tony Stark playing a game aboard the Benatar where the song is presumably playing off Star-Lord’s Zune.
And just like Rubberband Man, Dear Mr Fantasy’s lyrics are incredibly significant for the opening of Avengers Endgame.
The words talk of the current sadness following the defeat at the end of Avengers Infinity War, while also mentioning Thanos’ Snap – the cause of the situation. They read as follows:
Dear Mr Fantasy play us a tune
Something to make us all happy
Do anything, take us out of this gloom
Sing a song, play guitar, make it snappy
