No Melodyne vocal tuning program needed here. In this era you had to be able to sing and she was note perfect, even live. You'll not find anyone on XFactor sounding like this, they clowns would most likely knock her back anyway lol.
My big sister passed away at the age of 39 in 1992 leaving a kid of 4 years. This song always reminds me of growing up in the 60s with her. She would be so proud of her lad today who is now a music & English teacher. RIP Cathy.
Nothing better than a warm summers day, driving in the car with the roof down and this belting out. Pump it up, pump it up, solid rock at its best.
