There are certain singers that stick to the point of singing in various bands/projects, in no way willing to form a permanent act (or not capable of, anyway…) for a long time and perform only via this one. To the point: count the bands/albums Graham Bonnet, Joe Lynn Turner, Jeff Scott Soto, Tony Martin, Glenn Hughes etc have been involved in. I think Lee Small will be an ‘anticipated’ addition to the list in the near future.
