The Smurf Band is the name given to the band formed by Glammy as the leader and singer of the group, alongside Meteorite and Rocky as its secondary members in the 2021 TV series.
In "Who's In The Band?", the band hosted a concert for Willow's birthday. During the episode in question, Glammy behaved like a diva, as pointed out by Meteorite and Rocky, which caused him to temporarily leave the group with Vanity taking his place. However, after Glammy felt bad for making a prank on Vanity which involves stretching his tongue with a lotion, he offered Vanity that he will make things right by masquerading as him during the concert, which caused Meteorite and Rocky to allow Glammy to rejoin the band.
This band replaces the Smurf Orchestra from the comics and 1981 TV series.
