A Sentimental Journey was written in 1941 by Les Brown and Ben Homer.
After a delay in releasing it as a single, the eventual release luckily coincided with the end of World War Two and it became a #1 hit for Doris Day and her band.
This song became the theme song for soldiers returning home from the war.
In the context of a funeral or memorial, the lyrics could be about a person returning home to the afterlife and looking forward to reuniting with other loved ones that have passed away.
Gonna set my heart at ease
Gonna make a sentimental journey
To renew old memories
Spent each dime I could afford
Like a child in wild anticipation
Long to hear that all aboard
I’ll be waitin’ up at heaven
Countin’ every mile of railroad track
That takes me back
Why did I decide to roam
Gotta take that sentimental journey
Sentimental journey home
