I'm playing in a couple of cover bands. The singer in one of the bands wants to begin introducing originals into the setlist. Currently there is no clear band lead but we all get along great and this band is about the songs and the hang, we aren't looking to make a living out of it. If I'm being honest I haven't exactly been blown away by the original songs I've heard so far and I'm concerned bringing these songs in and egos getting bruised if/when other BM want to change or otherwise have input to those songs. Anyone got tips for integrating originals into a setlist and navigating the potential pitfalls of disagreement when it comes to including that kid of material?
I've had two cover band experiences where members came up with originals and wanted to bring them to the band. In the first case, the member realized on his own that they were an indulgence and only ever asked the rest of the band to help him out in the studio, and while there was the kernel of the idea, we never played his songs out...there was never any pushing.
I'm currently in a band where the lead singer and guitarist had some things they put together and did an EP. We incorporated 4 of the songs at one gig that was partially promoted as a "release event" for the EP. Currently, we include one. Again, it's fortunate that these guys realize that their originals are a personal indulgence, so there's not any pushing or grand schemes behind it, and a decent part of our turnout at any given gig are fans/friends.
It sounds like there might be an issue of your singer thinking that people will want to hear and will react differently to their music than is probably the reality. Again, in these scenarios, we were fortunate to not have a lot of ego behind any of it and fairly realistic ideas and expectations. If it comes to serious disagreement, I feel for you but wouldn't have any experience that might help.
That said, to your question of "how?" more directly, I think it helps if you are playing to largely friendly/close audiences. That is, that these are people who are there to see you...if you have "a following", them; if it's really friends and family that come to see you, them. In situations where the place is the attraction and your band is incidental, IMO, don't bother with the originals because you will interest that you potentially gained.
Do you have studio recordings? Are you active online? In promoting a gig with a friendly audience or a good portion of the draw being fans/friends, use the song...post it online and people can click and take a listen. Like above, include in the promotion that it's something special as far as the first public performance of the material. For those people paying attention and already "fans", it's not out of the blue. If it's something with a hook, there might be some familiarity already...maybe even anticipation. In time a good song or two can be nice additions that some people are looking forward to hearing when they see your band.
Good luck with it.
