Wolfmother frontman Andrew Stockdale has been fined $350 after a drunken attempt to sing at a Brisbane bar on Sunday night.

Stockdale, 35 of Paddington in Brisbane's inner-west, did not appear in Brisbane Magistrates Court this morning but his lawyer entered guilty pleas on his behalf for offences under the Liquor Act.

The court heard Stockdale was drunk at the Archive Bar in West End at the weekend when he tried to jump on stage to sing.

Defence lawyer Noel Barbi, for Stockdale, said the band playing at the time "took exception to that".
