They have not told me what the theme is. They usually leave the number of songs up to me. I think that I will probably do 2, 3 at the most. We are celebrating our 36th year I believe.
I would do something from the 70s, which would represent the time period that your church was birthed.
Then, I would do something (perhaps from the 80s or 90s) in tribute to your pastor, whether a favorite song of his, or something he used to dig or request a lot...
Lastly, I would do something modern (as in, from 2007).
For a 70s song, I would go with the Hawkins... they put out some great stuff back then, a wealth of songs.
For something modern, I would go with John P. Kee, Hezekiah, or Ricky Dillard, because they put out great choir music.
