The Purple Hearts were an Australian rock group, formed in Brisbane in 1964. The band consisted of lead vocalist Mick Hadley, lead guitarist Barry Lyde (known as Lobby Loyde), rhythm guitarists Paul Steffen (1964-65) and Fred Pickard (1965-66), bassist Bob Dames, and drummers Adrian 'Red' Redmond (1964–66) and Tony Cahill (1966-67).

It is notable that Brisbane, traditionally the most conservative of Australia's state capitals, has fostered some of this country's most anarchistic rock bands from The Purple Hearts to The Saints. The Purple Hearts were tough, arrogant and pioneering and Lobby Loyde is widely acknowledged as Australia’s first true rock guitar hero – busy blowing up speaker boxes before high volume and feed-back became rock staples.
