The white cliffs of Dover

This is a classic take on a classic song, and it includes the less well-known introduction to the song, as well as the very well-known chorus. Some of the harmonies are quite spicy, and need careful work to tune well, but it is definitely achievable by a non-auditioned amateur choir. The “instrumental” section features flowing, interweaving lines from all voice parts, and the key change towards the end helps to lift the final section.
