In 2015, Smith officially left the band after not performing live with the band since his departure in 2013. Shortly thereafter, Weekes reverted to being a touring member once again, resulting in Panic! transitioning to a solo project presented by Urie. In April 2015, "Hallelujah" was released as the first single from Panic! at the Disco's fifth studio album, "Death of a Bachelor" (2016). In December 2017, Weekes officially announced his departure from the band. In March 2018, Panic! at the Disco released "Say Amen (Saturday Night)", the lead single from its sixth studio album, "Pray for the Wicked" (2018), which was released in June.
