Hey! Hello! are an international power pop band, formed by the English singer-songwriter, Ginger Wildheart. The band's initial incarnation for the debut album consisted of Ginger Wildheart and New York City-based singer Victoria Liedtke. Liedtke was replaced by Love Zombies singer Hollis Mahady in 2015, with Toshi, Ai Sugiyama and The Rev joining the lineup. Mahady left the band in 2016, and auditions were held to replace her.
According to Ginger, the band's name was chosen by his son, who had misheard the Ramones lyric "Hey Ho, Let's Go".
