I totally agree with "Guest" above.You can practice and practice at home but it's not until you've tried out a song in public that it begins to gell. You have to start somewhere and in my experience most songs improve rapidly after the first couple of outings. We usually ask that people don't join in until we are confident but this does sometimes fall on deaf ears."Bear with bear with" for those of us who like to learn new songs rather than keep trotting out the same old 'favourites'.
