How should one enter the artist name, when f.ex. the label says (example translated from danish, but I believe it is very common on particularly older records): "Paul Godwin's Orchestra. Refrain: Viggo Larsen". Is it (1) Paul Godwin and Viggo Larsen, (2) Paul Godwin, Viggo Larsen - or just (3) Paul Godwin (with full credit shown in a note)?
The problem was outlined a bit by Whyperion on 27th January in the first paragraph. It seems that in the earlier days the orchestra was often the "main" artist and the singer somewhat in the background.
