Pete Doherty is more focused than ever following his recent stint behind bars, according to Babyshambles drummer Adam Ficek.
The singer was sentenced to three and a half months in jail on 8 April for missing court appointments and using drugs while on probation.
He was released on May 6 after serving 29 days.
Ficek told Newsbeat that Doherty had been pulling the band in for rehearsals every day since his release to prepare for their comeback show which took place at the London Forum on Tuesday night.
"We drove up to his house and saw him and he was really on good form," the drummer said.
"He seemed really focused. He came out of there really knowing what he wanted to achieve and it was him that was calling for rehearsals.
"He was saying, 'Right we have got to rehearse every day, make a new song every day to get ready for the Forum.' So all respect to him for that. He's had some time to think in there and he's back on his game."
Ficek revealed that Doherty wrote several new songs in prison and the band are hoping to showcase a host of them at the London gig.
"He's so prolific I think he always writes, it's just that he had a pen and paper in there," he said.
"He's been throwing songs at us left, right and centre since he came out. We have six or seven songs banding about so we're hoping they will make an appearance. There's a song called The Natives At The Gates Of Rome which has a tribal lilting feel to it."
Despite Doherty's recent relapse, Ficek said the band are rallying around their singer to ensure that he stays clean.
He added: "It is always a concern it will happen again. In his mind he always wants to stay focused and clean and free from all those problems but as anyone knows who has dealings with anyone who has addiction problems, it is sincere when they say that but there are times when they are going to fall.
"Unfortunately Peter is in the position where wherever he does fall people are in the position to take a photo or have a kick at him when he's on the floor.
"But his pledge is always to remain on the straight and narrow. It is up to us and the people around him to try and maintain that integrity and keep him on that good path."
Babyshambles are due to follow up their London gig with two further shows at the Manchester Academy on 17 May and Glasgow Barrowlands on 19 May.
