I would say just write it as a normal letter, addressed to more people

If I'm writing to a band, e.g. New Found Glory, then I'd address the envelope to 'New Found Glory' and then address the letter to all of them.

Well you should address it to the band, unless you only want certain members. After you've talked about them and their music etc., just say something like "Would it be possible for you guys to sign my picture for me please?".

When I write to bands I do it a couple of different ways, If it's an all guy band I'll start it out like "Hey Guys!" and sometimes if it's a band like Casting Crowns I'll just put "Dear Casting Crowns". The band members will more than likely pass the letter around so the whole band can read it. {thumb2}

Well, speaking from my experience, I've found it's best to address your letter to the whole group (eg: To Rascal Flatts or Dear Kings Of Leon) and then just write the letter exactly the same as to a solo artist. In your actual request, just say something like "if it's not too much trouble could you all sign my photo?"
With groups, it's always best to write to them via venue {thumb2}

Hope this helps. Good luck

you could say:
i was wondering if, when your (group/band/ friends) had some time, if you all would be able to sign this photo for me. I would not be able that that you enough.


and that just might work

i know theres many ways to ask if they can sign my picture ttm, but my
question really is how to ask them to sign my pictures
when theres like 5 people in the group?
also who do i address it to?
thanks for you'll time. {thumb2}
