GTK (standing for "Get to Know") was an Australian popular music TV series of ten minute episodes, produced and broadcast by ABC Television from 1969 to 1975.
Ric Birch, aged 24, the ABC-TV network's youngest ever television director, devised a program that would attract teenage viewers, and in less than six weeks, made four pilot shows.
The band chosen as featured group for the week would often record their own 'cover' version of the GTK theme (composed by Hans Poulsen), which was played at the start of each of the programs.
These live performance segments were recorded to videotape in Studio 21 at the ABC's Gore Hill, Sydney complex, which had originally been used for drama during the early days of live-to-air production.
Another aspect that makes this GTK footage important is that many of the bands were asked to play material from their live repertoire—including cover versions—rather than their current or recent hit song/s, since it was felt that the groups would perform these better, and because it would show off other facets of their music.
Estimates from the ABC have indicated that almost 100% of the series has been saved, which included interviews with Pete Townshend and Marc Bolan and colour footage of Lou Reed's 1974 Sydney concert (including one of the earliest known films of Reed performing "Walk on the Wild Side") and his disengaged Sydney press conference, which features noted Australian television journalist Ian Leslie.
