Drew, who plays the drums for Fender, shared a message whilst watching Glastonbury in 2014.
He said: "My Dad's band is currently headlining the Avalon Stage at Glastonbury.
"What a way to raise the bar for me."
The Tweet was shared at 23:48 on Sunday, June 29 2014, which coincides with the time that Peatbog Faeries were on the Avalon Stage.
Fender posted the Tweet and called it a 'crazy and beautiful' interaction to come across ahead of playing Glastonbury tonight.
He said: "How crazy and beautiful is this interaction between our Drew and his dad considering what' happening tomorrow?"
The 'Seventeen Going Under' singer will take to the hallowed Pyramid Stage at 8:15 pm on Friday.
In a separate message shared online, Fender said: "I've always wanted to go to Glastonbury Festival and always dreamed of playing the Pyramid Stage as a young lag.
"Tomorrow I'll do both."
Fender fans in the North East not in attendance at Glastonbury can watch and listen to the set live on the BBC.
The Geordie star has been given an hour-long set, which finishes at 9:15 pm.
