The four rockers will go their separate ways after a farewell gig at The Golden Vine on tonight.

Lead singer Steve Saxton said the band’s drummer, Mik Weir, couldn’t keep up his commitment to the band.

“He plays with another band, fills in for The Rebels in Melbourne and is working full-time as a teacher,” Saxton said.

“We’re a group of old mates and it didn’t feel right continuing without him.”

Berlin Postmark began as a band of mates in university who reunited two years after time apart.

What was supposed to be a one-off gig turned into a two-year adventure that saw Berlin Postmark release a single on iTunes (I Don’t Believe You) and play alongside The Whitlams at Big Hill Vineyard and playing the prominent front stage at The Espy in St Kilda on a Saturday night.

“We were only supposed to play one gig (two years ago) and had good time, got a bit serious about it and had a lot of good supports,” Saxton said.

“We threw in our holidays, spare time and money and gave it everything and gave it a crack for as long as we could.

“But being in our mid-40s and working full-time, we have different responsibilities.

“If we weren’t all old mates, we would replace (Mik) and keep going.”

Saxton doesn’t intend on throwing in the musical towel just yet, with the lead singer and guitarist working with some other bands.

“It’s not about how old or young you are; it’s how much passion you have,” he said.

The gig at The Golden Vine will give the band a chance to show how it has evolved over the years.

“It will be the longest gig we have ever played, something like a 16-song set,” Saxton said.

“We’re up first and some of our mates (The John Grossman Project) are finishing it off so we can have a good time.

“(The Golden Vine) is where were started so it’s where we want to finish.”

Berlin Postmark’s single I Don’t Believe You is still available on iTunes.

The band’s farewell starts at 8.30pm tonight at The Golden Vine.
