Thanks to Madam, I've attended a fair share of weddings here in Nigeria. Mostly in Lagos so far.
Once, we arrived early and managed to witness the traditional part of the ceremony. The elders of both families would meet and sat in front of each other, especially both bride's and groom's parents were present. During Fadamewa's and Richard's wedding, there were two ladies as the MCs (emcees or Master of ceremony) and every few minutes they will break into sing song about the ceremony.
Also with sing song and jest, they invited the groom to meet his future in-law. The groom and his entourage would enter the hall dancing...all happy and smiling before the MCs dropped the heavy end on them.... Ah! Some Naira (money) is needed to proceed... Both MCs would bully/pester him to deposit some money into the waiting container. Of course the groom and his entourage would comply... Eyes on the asking for some money...of course he complied. Eyes on the prize broda (brother).
