This was one of the songs I learnt to play on a guitar during my college days. The chords are easy to handle. Great for beginners. Even now when I pick up my guitar, I invariably would strum this melody. This and a few others form the basic repertoire of songs when I while away in the wee hours of the day.
First, a bit of introduction of the song and the group New Christy Minstrels:
"This group was the brainchild of Randy Sparks who named it after the folk/balladeer troupe "Christy Minstrels" formed in 1842 by Edwin P. Christy. The idea was to bring together a collection of unique talents be they vocal and/or instrumental into one "super-group", and the New Christy Minstrels met with a lot of success early on. "Today" is a song recorded for the soundtrack of a Glenn Ford comedy called "Advance To The Rear", and through the spring and summer of 1964 was a huge hit reaching #17 on the pop charts. Among the many members the New Christy Minstels have had included Kenny Rogers, Kim Carnes, Barry McGuire, The Byrds' Gene Clark, and The Association's Larry Ramos."
John Denver's version is probably more popular but the harmony of the voices done by New Christy Minstrels tips it in their favour.

There is a Cantonese version by 關正杰 although it does not sound as good as the original version. Here it is:
