Because the track is unlicensed and its originator remains anonymous (or possibly deleted), it is not available on Spotify or Apple Music through official channels. However, you can find high-quality versions on:
Erika, Erika, I’m on my knees
My canteen is empty, my heart’s a breeze
Fill me up, fill me up, with that heather-sweet tea
Erika, darling, pour yourself over me.
The song exploded when a Bundeswehr reservist, @feldwebel_fiona, posted a video of herself marching in combat boots while lip-syncing the line “Fill me up, I’ve been marching for miles / Give me your rations, give me your smiles.” The video cut to her pouring a canteen of water over her head.
