Nigerian music Legends, Ebenezer Obey and King Sunny Ade faced this same problem in the '70s, infact, at some point, some of their band members were told to swear to an oath, that they will not run away whenever they take them out of the country for engagements. I never knew it still happens.
Acclaimed gospel musician, Yinka Ayefele has asked US authorities via a statement to track down and deport 3 of his band members Ojoyido Adegbenga Ezekiel (Keyboardist), Solomon Olugbenga Motimoke (Vocalist) and Olusola Kayode Isaac (Vocalist) who disappeared after arriving the US for a six-week tour.
According to his Publicist David Ajiboye, "Olusola Kayode Isaac defected at the
LaGuardia Airport, New York on Monday 14th October on his way from Houston with three other members of the band, Ojoyido Adegbenga was said to have
disappeared from the group at the Howard Johnson Inn on Rockaway Boulevard, New York on Tuesday,15th October. The third man Solomon Motimoke (Yatty) left the band while still at Washington DC on 11th October"
