1968 was also the year Classical Gas went to #1 in the United States. It was written by Mason Williams, who was (at that time) head writer for The Smothers Brothers Comedy Hour. Very talented guy.
Also that year, 1968, MacArthur Park went to #1. Perhaps Jimmy Webb's magnum opus.
A remarkable year for music, and to be young. That year would end with the Book of Genesis coming to us from lunar orbit.
I don't know why, the lyrics never made a bit of sense to me......
MacArthur's Park is melting in the dark
All the sweet, green icing flowing down
Someone left the cake out in the rain
I don't think that I can take it
'Cause it took so long to bake it
And I'll never have that recipe again
Oh, no
What a great time for music it was. That music crossed age barriers. It was decent,, with great melodies.
