Lots of people affected by cancer get great enjoyment from singing in a choir, like tenovuscancercare.org.uk You can call
0808 808 1010 free for 365 days a year. And, if you live that way, you could join the Guildford choir. They meet every Monday 6.30pm - 8pm at All Saints Church, Onslow Village, Guildford GU2 7QJ (free parking).
I cannot upload their leaflet on tho this site, but it does show a group of people really enjoying themselves, and it says:
Singing is a powerful force. It unites people, improves well-being and it makes you happier. The best bit is, everybody can sing - even if you don't think you can!
Our Sing With us choirs are for anyone affected by cancer. We have a choir near you and new people are joining us all the time. Pop along whenever you like, for a sing and a cuppa.
