Teenage Mailbag was an Australian television series which aired in 1957 to 1958 on Melbourne station HSV-7.
According to a 2008 article in The Age, the format consisted of Ernie Sigley, Gaynor Bunning and Heather Horwood singing requested songs in a 15-minute slot, and later expanded to an hour.
[1] The one-hour version became the series The Teenage Show[2] (1958-1960?).
At one point, the series aired at 7:15PM, preceded by another 15-minute series titled Take That and followed by an American program (The Adventures of Rin Tin Tin).
[3] It should not be confused with an unrelated 1960s series by the same name which aired on TCN-9 in Sydney (see Teenage Mailbag).
