Thanks for help everyone.

Yes Mummycat, same one! :o) I meant Grove centre on Jews Walk - they contacted me and said they did not have rainbows anymore. I contacted the Normanton Road troop (thanks Roz), lovely leader was very helpful, but probably unavoidable clash with brother's beavers on same night... So was just hoping there was a Rainbows not on a Tuesday!

thanks again, love these forums, don't know how I ever found anything out before this...
