Love it! Yes, you definitely can write a song using only 2 chords and yours is a corker, both lyrically and with added instrumentation. Way back in 1969 when I was 18 and in my 2nd band in which we only played our own material I wrote a 2 chorder that worked perfectly for drums, bass and guitar with a separate vocalist - I was a drummer back then and learned to play guitar as I was most interested in writing songs. Sometime in the 80s I rewrote the lyrics and that version is the only song I have on YouTube with my vocals and only playing an Eko Ranger I've had since around 1976. But I only recorded that 10 years ago when testing a new microphone, so besides it being unrehearsed the guitar wasn't tuned to standard pitch, so I've not been able to adapt it using BiaB. Thumbs up for the 2 chord song! laugh
