Is there a more lovable song than "Mary's Prayer" by Danny Wilson? It's always welcome, always warms your heart, always makes you sing and smile. That song, which reached #23 in the US in 1987 was written and sung by this week's guest, Danny Wilson frontman Gary Clark. As much promise as the band had, they only managed two albums before calling it quits at the end of the 80s. Gary spent the dawn of the 90s starting a few other groups and working on solo material to no avail. As luck would have it, he eventually began collaborating with the right people and he went on to write many hit songs for other artists like Natalie Imbruglia and Demi Lovato. After years of success, he got a call from movie director John Carney ("Once") and was asked to do the music to the wonderfully beloved 2016 film "Sing Street". Today, that relationship has even more projects in the works! So, this seemingly one-hit wonder has made it work successfully for over 30 years. Who knew!
