J5 had a lot of good songs to me. though like you said they would probably dig deep to find them. maybe they not willing to do that. funny they do it to Michael why not his early days? maybe they just not in to it though that's history. when Michael was alive. he always did the old Motown songs in concerts etc because he knew where he came from and never forgot it.
I don't know. but it's sad that his Motown old songs are not being recognize today. I wouldn't call them outdated or anything. some of them sounds like they could be made today. or maybe I just have an old soul. hahaha.
last year they did rerelease some of J5 records etc. some people brought them to add to their collection.
so there are people who do listen to J5 songs just not, many? I guess?
I think if they did release some concerts people probably be more interests in them.
Keep in mind they was a boyband. so most of their fans was really teenagers during the time. though that's not saying they had adult fans as well. they had a mixer of both.
