Owen Doyle (left) and Ki Fitzgerald said it was "half-time" in their battle
Two original members of boy band Busted have said they would appeal after the High Court rejected their claim for royalties totalling millions of pounds.
Ki Fitzgerald - whose stage name was Ki McPhail - and Owen Doyle said they co-wrote songs but were forced to sign away their rights before being sacked.
However the judge, Mr Justice Morgan, dismissed their case and questioned their reliability as witnesses.
They said they were "disappointed" and would continue to "fight for justice".
Fitzgerald and Doyle were in a band - The Termites - with future Busted members James Bourne and Matt Willis for the first nine months of 2001.
They went on to form Busted together but Fitzgerald and Doyle were fired shortly afterwards.
Busted eventually split up in 2005.
A statement issued on behalf of Fitzgerald and Doyle added they would now be recredited as "original co-owners" of selected Busted hits, including their 2002 single What I Go to School For.
This element of the case, which ended on Friday, had gone unreported until now, the statement claimed.
