Canada-based Hidden Cameras boast 15 members! You wouldn't know it by the sound however - it's lush, but no way near orchestral.
Miracle does definitely have that folk ensemble feel to it though, as the acoustic guitars, cello and double-tracked, vibrato vocals ease you along in a scenic stroll.
The chorus lyrics grate slightly with repetition, but the overall feel of a pretty melancholy compensates for this and as the song pleasantly wanders into a dreamscape, so do I.
