Louis Tomlinson released a new music video for a song titled "Two of Us" yesterday, and it has his fans feeling some feels.

In the video, Louis Introduces 83-year-old Richard and the pair go about crossing off some of the items on Richard's bucket list.

Richard lost his wife to Alzheimer's in late 2016. Around the same time, Louis lost his mother to cancer.

Louis said on Twitter that he learned a lot from Richard, who he describes as a:

"fearless man who in light of tragedy still pushes himself to live with as much laughter and happiness as possible."

The video is structured more like a mini documentary, with "Two of Us" playing quietly in the background. The focus is really on Richard's story.

After talking about Richard's life up to now, the pair set off to do some of the more spectacular things on Richard's bucket list.

These included flying a helicopter, driving a race car, getting a tattoo (though he actually ended up adding his art to Louis' ink instead), and riding on a roller-coaster.

Louis was right by his side the whole time, and the pair seemed to be thoroughly enjoying the experiences.

The final event that Louis arranged was possibly the most special of the bunch.

Richard, in addition to other such jobs as taxi driver, an actor, and serving in the RAF, had also been a lounge singer until his wife's condition progressed to the point that she could not be left alone for long periods.

Tomlinson told Richard as they exited the roller-coaster that he had a little gig lined up for that evening and wanted Richard to come.

Little did Richard know that the "gig" was a sold-out arena performance.

Richard took to the stage and performed an excellent rendition of Andrea Bocelli's "Con Te Partirò" to raucous applause from the audience.

At the end of the video, Tomlinson tells Richard how much he enjoyed their time together.

"It's been lovely. I mean, honestly, no bullshit, actually spending real time with you and feeling like we're getting to know each other has been real nice."

Many praised Louis and Richard for supporting each other.

Others were taking Louis and Richard's friendship as an example.

Some reminded folks that they can help by donating to Alzheimer's and cancer research.

True friendship can be found in unexpected places,and shared grief can being a deep understanding between people.

Allowing yourself to see others around you, regardless of age, can open up the opportunity get to know some amazing people.
