What is ‘America the Beautiful’?
The backstory:
‘America the Beautiful’ is a traditional song that dates back to the 1800s. It was originally written by Katharine Lee Bates as a poem called "Pikes Peak". It was later put to a hymn by Samual A. Ward.
The combination of Ward's melody and Bates's poem was first entitled "America the Beautiful" in 1910.
One of the most notable modern-day performances of the song was by Ray Charles, whose soulful version peaked at number 98 on the U.S. R&B chart in 1976 as America celebrated is bicentennial.
