interesting, i fasted lent before becoming orthodox.
it wasn't a proper lent fast, with abstaining from eating and drinking till a certain time, but i cut out most animal products.
although i wasn't benefitting from the sacraments, i did have orthodox friends praying for me, and i think i wanted to show the people around me that it was not the end of the world, and i wouldn't suddenly become very thin, or a nun, or drop dead (all things people non-accustomed to orthodox fasting may fear!) i expect there was an element of pride involved, but it was more complicated than that.
i broke my fast at midnight, with my closest friend watching closely to see if i would gorge heavily (thus proving the fasting was not beneficial). i suppose becoming orthodox at that stage would have been too much of shock to too many people close to me, so i was trying to be as orthodox as possible, without actually joining the church. i smile now when i think that all i was looking forward to was a cup of milk, small steak and a glass of wine!
i didn't know then that the most wonderful part was the paschal liturgy with the beautiful Holy Communion.
as for music, i'm all for loud music at the right time, with the right theology.
in our church we have a hymn that is sung quite loudly in holy week:http://tasbeha.org/media/index.php?st=Hymns%2FHoly_Week%2FElshahid_Abu_Fam%2Fcd1%2Ftrack5.251.mp3
saying, 'yours is the power, the glory, the blessing and the majesty...' and it is often sung quite fast. the 2 sides of the church take turns singing it and then we all join in at the end. there is a lot of repetition, so most people, kids and adults join in.
but what actually makes going to church exciting is the effect it has on your life, the ability to forgive and to love enemies and to know the love of God. i think kids generally need encouraging to share how God makes their lives different in a practical way (eg. i remember one 4 yr old from my protestant days, explaining how being a Christian meant not hitting his brother when he was being annoying!).
may God bless u all in your journey, take it at God's pace, and take many people with you.
