Aside from being friends, country music legends Willie Nelson and Glen Campbell took Nelson’s “Funny How Time Slips Away” to the recording studio and teamed up for a duet.  With its chilling and tear-jerking sound, the song left the fans emotional.

This heartbreaking ballad was Nelson’s 1961 hit. The two legends recreated the song in a duet. It was then featured on Campbell’s final album, Adios. As for Campbell, he used his final album to record the tunes that were close and dear to his heart. And, the result was amazing. His album, Adios, earned him his first posthumous Country Music Association (CMA) Award.

Together with Nelson, Campbell stole the hearts of country music fans with the compilation of their songs. The impressive vocals and wonderful harmonies truly exuded on the album.

In addition, this decades-old classic talks about a powerful message of old friends that unfortunately parted ways. They then realized how much time had passed them.

It’s been so long now,
But it seems now, that it was only yesterday
Gee, ain’t it funny, how time slips away.

While they sang about similar emotions and heartache, Nelson and Campbell’s superb vocals brought a soulful blend of two contrasting sounds.

In an interview with Rolling Stone Country, Carl Jackson, Campbell’s longtime friend, shared about the singer’s difficulty recording the song.

“Sometimes we had to do a line at a time because with Alzheimer’s, his memory of the lyrics, as we saw in the tour he had to use teleprompters, that went away pretty quick. But his melodies did not go away for a long time after his ability to remember actual songs… I can’t explain it.”
