happiest, I think this is what you are looking for:
On MBD‘s “Once Upon A Niggun” album, song #4 is called “Emunah & Bituchon Medley”. It starts out with eerie music and the sound of a train rumbling down the tracks. And then comes MBD singing “Ani Ma’aminim, Ani Ma’aminim, Ani Ma’aminim…” He is then joined by an adult choir and child. The song then moves on to “Vhaya Bayom Hahu”. And then comes “Mimkomcha Malkeinu”. After Mimkomcha, they return to “Ani Ma’aminim”. The song ends with a child calling out Ani Ma’aminim and the train. VERY heart wrenching song!
Here is the album on MostlyMusic.com:
