Some additional info on "Happy Land":

Southern Harmony (per this web page) has "We'll" instead of "reign", and transposes verses 2 and 3. This transposition also occurs in The Social Harp (1855), per the lyrics given by The Boston Camerata on The American Vocalist. Both of these other sources have "live" instead of "dwell" in the 3rd (their 2nd) verse.

The Southern Harmony page gives Leonard as Breedlove's first name.
