Did You Know? Have You Ever Seen The Rain was written by John Fogerty. 

It's about rising tension within the band and the imminent departure of his brother Tom. It was written about the fact that they were on the top of the charts, and had surpassed all of their wildest expectations of fame and fortune. They were rich and famous, but somehow all of the members of the band at the time were depressed and unhappy; thus the line "Have you ever seen the rain, coming down on a sunny day?". The band split up the following year.

Did You Know? Jim Croce wrote I'll Have To Say I Love You In A Song for his wife Ingrid. She retells the story of how it came about - 

'One weekend, after being on the road for many months, Jim got a chance to come home to relax with his family. We settled in to enjoy our time alone together. Though Jim was expecting company the next day, avoiding confrontation he never told me that we were to be joined by an entire film crew! The next morning, 15 people from Acorn Productions descended upon our house to record a promotional film of Jim Croce at Home on the Farm. I prepared breakfast, lunch and dinner for the whole film crew and after the group left, I questioned Jim about our finances. After a year and a half of his working so very hard on the road, we were barely making ends meet, but Jim wouldn't talk about it. He hated questions as much as he hated confrontation, especially about money. He stormed out of our bedroom and went down to the kitchen table to brood. The next morning he woke me gently by singing his new song. 'Every time I tried to tell you the words just came out wrong. So I'll have to say "I love you" in a song'

He then quickly got off the phone and started to write the song. 

As it didn't come together he showed it first to Johnny Christopher to contribute too and then Mark James and they completed it together.

As Mark James previously write Suspicious Minds for Elvis, it's assumed that Always On My Mind was written for Elvis, but Carson explained it was written for for every man, 'it was one long apology. It’s sort of like all guys who screw up and would love nothing better than to pick up the phone and call their wives and say, "Listen, honey, I could have done better, but I want you to know that you were always on my mind.'"
