This day in music history.

April 16, 1956, Buddy Holly releases his first single, "Blue Days, Black Nights". The song did not chart.
Blue Days Black Nights
Blue days - black nights
blue tears keep on fallin'
for you dear
now you're gone
blue days
black nights
my heart keeps on calling for you dear
and you alone
Memories of you make me sorry
I gave you reason to doubt me
but now you're gone and I am left here all alone
with blue memories
I think of you
Blue days - black nights
I didn't realize I would miss you
the way I do
and now somehow I know
I will pay
for the times I have made you blue
