If you liked the finale of the St. Paul's Suite, try Frank Bridge's Sir Roger de Coverley. It's a series of variations originally composed for a string quartet then orchestrated by Bridge - although it's most often heard in its strings-only form. It starts with Bridge teasingly hinting at the tune, then becomes more animated and dance-like towards the end. At the last, the piece's melody is masterfully blended with Auld Lang Syne. It's really quite brilliant.
