Antti Hammarberg, Paul Fagerlund profile

Rudolf Holtz was a fake artist name Antti Hammarberg (Irwin Goodman) and Paul Fagerlund occasionally used for crediting their songwriting collaborations. One reason for this arrangement is that at the time (late 70's) Hammarberg had enormous tax debts, which were claimed from his royalties. Fagerlund owned the legal rights for Rudolf Holtz's name, collected the royalties and paid Hammarberg his share leaving tax officials empty handed.
