The Blue Mountains Ukulele Group will go "off the rails" on Australia Day as they sing and play their way up the Blue Mountains.
The Blue MUGs will begin by playing a set of Aussie favourites at the Glenbrook Gnome Festival in Glenbrook Park at 10am.
From there they will continue up the Mountains, stopping at pubs along the way to give the locals a taste of their own raucous brand of ukulele pub rock.
The tour will finish at the New Ivanhoe Hotel in Blackheath in the evening.
"This is a big day for the group, involving a lot of travel, a lot of strumming and a lot of singing," said Steve Roberts, Blue MUGs ukulele player.
"It has been rumoured that some ukulele players may even take the opportunity to quench their thirst at some of the venues.
"Anyone is welcome to join us; the journey is just as much fun as the destinations."
The event is a warm-up for the sixth annual Blue Mountains Ukulele Festival held at the iconic Carrington Hotel in Katoomba over the weekend of February 13-15.
The festival is the largest ukulele festival in the world with more than 100 acts across nine stages and thousands of visitors taking in the ukulele fun.
The Blue Mountains Ukulele Festival is a free event run entirely by volunteers and is known for its upbeat and fun vibe.
The festival has won awards at the Blue Mountains Tourism Awards and has become an icon of Blue Mountains tourism.
The festival kicks off with a dinner and show on the Friday night. Saturday is filled with performers and workshops across five stages. Sunday is a day for kicking back with your ukulele and playing along with all the new friends you have made during the weekend.
All are welcome; non-players will have a smorgasbord of free entertainment (and might even find themselves learning their first song on ukulele), beginners will learn so much and experienced players will be enthused and inspired.
