Pat is delivering a big box of lovely ukuleles for Reverend Timms's ukulele big band. Everyone is getting one, and as Pat delivers them he finds out that they all have a little problem they need help with. Happily Pat can help - whether it's tuning or plucking or keeping in time. Reverend Timms is overjoyed as they all arrive playing a wonderful tune for him - and the children have a special treat for everyone as they play a song they have composed themselves.
