Hey!  My first tab ever.
Basically, what I do is the chord combo of G, C, and D/F# throughout the song.
On 4/4 cut time, you play 4 quarter notes on each chord.  Go back and forth between the 6th & 2nd strings.
If *this symbol* is around the chord pattern, you strum.

And everything keeps moving on, moving on

[strum once on each chord]

In every day there comes a song with the dawn
