The song selection worked really well too, and one lady told me it was the best combination of songs we'd had. The irony is that I didn't actually select the songs with any purpose. I'm working through our song pool alphabetically, and these four just happened to fall together. When I looked at the 4 songs, I actually thought that they wouldn't work together, and I would never have picked them purposefully.
This reinforces a suspicion I've long had that music directors make far too big a fuss about song selections on any particular week. Indeed, I think they can fall into patterns of thinking that ensure we pick the same sorts of song combinations every time (eg. 2 quick ones to start, to slow ones to finish). My current theory is that you get together a good pool of songs, and then your choices can be random and it will work, week by week.
Oh, and for those who are wondering, the song list was - Come Thou Fount, Consider Christ, God of Wonders, and Grace Unmeasured.
