Under the circumstances you state then, no; you should plead 'not guilty'. The onus is on the crown to show that you committed the crime libelled. There is no evidence to support the offence libelled and can only succeed if witnesses perjure themselves and their evidence is preferred to you and your witness.
So far, all that has happened though, is that the police have submitted a report to the prosecutorial authority - the Crown Prosecution Service (England/Wales) or the Procurator Fiscal (Scotland). The police have no power to decide if your case goes to court. The CPS/Fiscal make that decision. If what you say is true then I would not expect this to go any further. One more thing:
I would be interested to hear opinions on the prospect of you raising a successful action against the arresting police authority for wrongful arrest. In Scotland, alleged misconduct requires corroboration - two pieces of connected evidence - e.g. the statement from the bouncer plus CCTV evidence or another witness, or even saliva on the alleged victim. Corroboration is not required in EnglandWales but even then, I would argue that 'reasonable suspicion' requires more than a simple single complaint from a complainer. On the other hand, even if the arrest was wrongful, perhaps it would be best just to put it down to experience and avoid going to that particular club again.
