Effros was a bugler in several Army regiments between 1917 and 1919, one of the rare situations when musicians have to get up early and aren't leaving town. After the war, Effros chose Baltimore as a base and began playing behind bandleader Bea Palmer. During most of the '20s, the trumpeter was a member of the Vincent Lopez Orchestra, an experience that provided him with many of the details needed to write the song Why the Twenties Roared with partner Phil Wall in 1927. Effros' compositions such as Cornfed were recorded by artists such as Fletcher Henderson and Red Nichols, as well as receiving several cover version treatments from bands back in his native England. Effros' own trips back to the merry isle for gigs must have been enjoyable, especially backing up the gorgeous singer Annette Hanshaw.
Lopez took his orchestra on an extensive European tour, but Effros soon seemed to prefer working in one place. He was hired as a house musician by the Vitaphone label during this period and became part of a clique of virtuoso studio hotshots such as banjoist Harry Reser. The trumpeter appeared on more than 125 different records during one ten-year period. In 1929, he was leading his own orchestra and recorded a Brunswick side entitled Sweet and Hot, which sounds like a tribute to Chinese soup. Effros continued to haunt the studios for the balance of his career. In the '40s he was also playing consistently with the D'Artega's Orchestra, eventually settling in Long Island. ~ Eugene Chadbourne, Rovi
