The protest was earlier championed by the musician but on Saturday, February 4; he released a video saying he was cancelling the protest due to security concern.
The singer said the protest was never his creation but a call to action to speak up for his people.
In spite of the cancellation, some Nigerians vowed to continue with the protest.
In Lagos, the protesters are expected to march from National Stadium in Surulere to the National Theatre, Iganmu, a distance of about four kilometres.
The protest is also set to take place simultaneously in Abuja, Enugu and Port Harcourt, among other major cities.
