In Mayday Parade, did Jason Lancaster write any songs?

I've been following Mayday Parade and Go Radio for a while now, but I haven't been able to find any reliable sources for this question. A lot of Go Radio's songs are pure poetry and they're absolutely beautiful, which makes me wonder if any of Mayday Parade's beautiful lyrics were written by Jason as well. Does Jason even write the lyrics for Go Radio? I know he did Forever My Father with his siblings, but other than that? Any input would be appreciated!
