Radio France has an amazing website that provides resources for teachers wanting to have their pupils sing. Logically most of the songs are in French, but there are four in English and several in German.
If you check out the songs available on the Ma chorale voix interactive site, click on "plus de filtres" and you can choose language as a filter. In English there is "I Will Survive" by Gloria Gaynor, "Imagine" by John Lennon, "You Don't Own Me" by Lesley Gore and "Ocean Eyes" Billy Eilish. For each, there are recordings of the music, sheet music and the lyrics, plus for three of them a teaching guide. On a similar theme to Imagine, there are versions in German and French of Beethoven's "Ode to Joy", it would be easy to adapt them to the lyrics in English.
