Dude3 is a band that Tom and Derek love.
- In the first book (The Brilliant World Of Tom Gates) Tom, Derek get tickets to a concert which is not far from where they live. Tom impresses Amy and she agrees to go with them as they have a spare ticket.
- In the sixth book Extra Special Treats (Not) Tom talks to June about Dude3 who states that they are rubbish.
- 7 of Dude3’s songs appear on Mix Tape (It's a CD really). Hints of the band’s music style are seen here, also showing that their song lyrics are very positive.
- The name Dude3 suggests that the band is made up of 3 members and they're classed as 'Dudes".
