*Burn With Me (Leaked September 2016) In this song Richie play the guitar and make backing vocals, it was taken in 2012-13, so this one belongs to WAN. Written by JBJ, RS & JS.

2018

When We Were US
Walls


A pity that we do not have Rage Of Angels and All We Are. Nor was that song released with Avici, I think it was called Love To Hold but I'm not sure.

I think I gotta rethink my opinion of Life Is Beatiful being the unused Peter Pan song from the HAND era.
Just noticed that Chris DeStefano was involved in the writing process and, since THINFS is the first album to actually show his involvement in a song (Rollercoaster), it's most likely an outtake from the This House sessions.
