Flyer
The Twisted Wheel (Whitworth Street)
11th April 1970

The exceptionally gifted Bob & Marcia hit the Wheel in April, 1970.

Wikipedia states:

Bob and Marcia were a Jamaican vocal duo that consisted of Bob Andy and Marcia Griffiths.

They had a #5 UK hit single in 1970 with "Young, Gifted and Black". They followed up with "Pied Piper", which peaked at #11 in the UK Singles Chart in 1971. Those two releases spent a total of twenty five weeks in that chart in a period of less than eighteen months. They discontinued their partnership in the mid-1970s, both feeling that it was not bringing them adequate financial reward.
