One of Haley's Swedish producers for her next EP (Anders is the other) released his Album including this duet w/ Haley.  You can listen to it on Spotify or purchase it on iTunes

Haley has been tagged on this new song by Drew as well as Balam and Mitchell Hauser (He produced “Some Way Some How”), so I’m guessing Haley contributed to background vocals, although if she did, I couldn’t tell as the BG vocals are multiple voices.  I could tell there’s a female voice, but to me it didn’t distinctly sound like Haley that I’d recognize it immediately 

Making his passing more tragic, Mike had just married in May:

This following the passing of another of Haley's friends, Scott Medlock, a couple days ago, who along w/ Robby Krieger started the St Jude foundation for children w/ Cancer, the charity event Haley had played w/ Robby the last few years.  

This article was written about Scott, his life, accomplishments and charity work a few weeks before his passing

Haley has also lost two (three?) aunts & an Uncle in the past year, also family friend and OG Halien, Penny, so you know what she's referring to when she's lost "so many people this year, it's unreal"  

If you've been following Haley along in her Instagram stories, she sometimes would make a post of introspection... I think these passings have weighed heavily on her
