For the first song, try "Danny's Song" by Kenny Loggins
For the early years, I like
"Watching Scotty Grow" by Mac Davis (covered by Bobby Goldsboro)
"House At Pooh Corner" by Loggins And Messina
"The Morning: Another Morning" by the Moody Blues (Days of Future Past album)
Balloons flying
Children sighing
What a day to go kite flying
Breezy school
Away from school
Cowboys fighting out a duel
Time seems to stand quite still
In a child's world it always will
For the later years,
"Simple Man" by Lynyrd Skynyrd
"New Horizons" by The Moody Blues
"Time Of Your Life" by Green Day
"Forever Young" by Rod Stewart
Them that can, do; them that can't... memorize Artist and Title
