Grandma singing to me

Grandma and I were going through her book collection again, and she came across a book that played songs and had a microphone that you could sing into. Correct that, it was supposed to play songs and it had a microphone that did not work. Either it was broken or the batteries were dead. In any case, that did not stop Grandma from entertaining her grandson and she sang the songs a cappella! I thought it was so fun and funny! I was extremely entertained! Please tell me where I can buy your album, Grandma!
