Listen to Debaba around the 4th attempting 2nd voice and listen to Ferre singing 2nd voice they sound exactly the same wow  , I hope Ferre can give us more of that voice and sound (by the way the two have extra ordinary voices), close your eyes and you'll think its Ferre singing.

 yeah indeed a lot of similarity
 on another note,dakumuda looks a bit like late deb's

Didn't notice that till now and the beard moustache
