Thanks for the info about the website.
I know about this website listing concerts in the Maryland area. The info, however, is spotty.
For example, I know for fact that the Bee Gees appeared at the Merriweather Post Pavilion in Columbia, Md in July 1975 but this is not listed on the site. Also the site is missing PLENTY of Civic Center shows.
I attended the Bee Gees show that is listed for 1979 (Capital Center).
So I'm still looking for the Bee Gees show at the Civic Center in 1974 or 1975.
Thanks for the info so far.
