Nightwing
Although Nightwing is commonly associated with Batman, the title and concept have origins in classic Superman stories. The original Nightwing in DC Comics was an identity assumed by alien superhero Superman when stranded on the Kryptonian city of Kandor with his pal Jimmy Olsen. Drawing inspiration from Batman and Robin, the two protect Kandor as the superheroes Nightwing and Flamebird. Following the Crisis on Infinite Earths continuity reboot in 1985, Nightwing was re-imagined as a legendary vigilante from Krypton whose story inspires Dick Grayson's choice of name when he leaves behind his Robin identity.
Nightwing (band)
Nightwing was formed when Gordon Rowley wanted to return to music, having left Strife due to heart attack. Gordon had done some session work between leaving Strife, also turning down a spot in Rainbow in favor of forming his own band. This led to the formation of Nightwing, with keyboard player Kenny Newton, guitarist Eric Percival, guitarist Alec Johnson as the core early line-up. With a variety of session drummers, including Paul Ellson, Steve Bartley, John Mylett. joining Rowley, Newton, Percival, and Johnson, "Something in the Air" was released in 1981, with "Barrel of Pain" by Graham Nash taken as a single release. For the tour and the following album, "Black Summer", Steve Bartley became the full-time drummer for the band, the group playing Redding Festival and supporting Gillan.
