Judging by the logo it looks like it could be the early to mid 1970's.
That logo was on our 73 Grand Final jersey but I think the one we all identify with came into being in 1976.
Where did you find that???
Mandy Sheridan & Terry King – From the Sharks Mouth (Unisound, 1976)
The Cronulla Leagues Club evidently decided to press up this album because their live entertainment was just that good. Terry King and Mandy Sheridan were the lead vocalists in the Sounds United singing group that feature on this album. The back cover uses all its space talking about the board members and how they steered Cronulla Leagues Club our of financial dire straits, so nothing is included about members of the band! The album delivers a variety of covers including ‘Mack the knife’, ‘Breaking up is hard to do’ and ‘I got love.’ They even do their own theme ‘Up, up Cronulla.’ The highlight for me is the quite nice version of Moondance that features Mandy on lead vocal duties and a rather groovy rhythm section. Worth your while if you can find it cheap. 1 x trade copy
