One of my previous jobs was creating midi versions of popular tunes, to be sold as ringtones. I admit sometimes spent a little too much time on them if it was a tune I really liked. The Mr Benn theme tune is one I was particularly proud of. Anyway, that’s all history, in the days before mp3 ringtones.
Back to the present, and some of my tunes now would make pretty good ringtones I think, particulary my 11 second tunes, released as the 11xEleven album.
