Braithwaite's Original Brass Band by Peter Stevenson

This wacky picture book by Peter Stevenson focuses on Braithwaite's Original Brass Band, which is supposedly the best band in the land. The band is comprised of a very odd looking group of heavily-moustached men who are clones of each other. One day whilst endeavouring to practise for the Oswaldtwhistle International Musical Championship, their instruments malfunction and  their notes float away into the sky. So they adventure into Outer Space to retrieve their music. They find themselves on a planet inhabited by little pink monsters and thus begins the  negotiation with the Maetstro (a conductor who collects the best bands in the universe) to regain their lost music. I really love the twist at the end when Great-Grandfather's old instruments from the attic are given a new lease of life. Author/illustrator Peter Stevenson has quite a number of books under his belt and his website is worth visiting. He has also written his first book in the Welsh language entitled Oes Ben Tylwyth Teg.  http://peterstevensonart.co.uk/books.html
