Mark, Don & Terry 1966–67 is a 1972 2-LP set compilation album by the American garage rock band Terry Knight and the Pack released on ABKCO Records in an effort to cash in on the March 1972 Capitol Records album "" by Grand Funk Railroad.
 The album has a plain blue cover with lettering similar to that of the plain black cover of the earlier Grand Funk Railroad release.
 Mark Farner and Don Brewer from Grand Funk had been in Terry Knight and The Pack with Terry Knight, who then managed them until 1972.
 Knight also managed the Ft. Worth Texas group Bloodrock until mid 1971.
I'm Alive is a solo album released by Night Ranger's drummer Kelly Keagy.
 Released in 2006 on Frontiers Records, it features Jim Peterik, Reb Beach, and Michael Lardie.
"We're an American Band" (from the album of the same name) became Grand Funk Railroad's first #1 single on September 29, 1973, Mark Farner's 25th birthday.
 Written by Don Brewer and produced by Todd Rundgren, its huge chart success broadened Grand Funk's appeal.
 It was sung by Brewer rather than Farner, who usually took lead vocals.
"Sister Christian" is a power ballad by the American hard rock band Night Ranger.
 It was released in June 1984 as the second single from their album "Midnight Madness".
 It was ranked number 32 on VH1's 100 Greatest Songs of the 1980s.
 It was written and sung by the band's drummer, Kelly Keagy, for his sister.
 It was the band's biggest hit, peaking at number five on the "Billboard" Hot 100, and staying on the charts for 24 weeks.
"I'm Your Captain (Closer to Home)" is a 1970 song written by American musician Mark Farner and recorded by Grand Funk Railroad as the closing track to their album "Closer to Home".
 Ten minutes in duration, it is the band's longest studio recording.
 One of the group's best-known songs, it is composed as two distinct but closely related movements.
 Its title has been rendered in various ways across many different Grand Funk albums, including "I'm Your Captain", "I'm Your Captain/Closer to Home", "Closer to Home/I'm Your Captain", "Closer to Home (I'm Your Captain)", and "Closer to Home".
The Mob was a one-off project (or "supergroup") consisting of Doug Pinnick, Reb Beach, Kip Winger, Kelly Keagy, and Timothy Drury.
 The band released one self-titled album in 2005 on Frontiers Records.
